A beloved retiree is living the dream.

He just moved down here where he could fish every day and just a real laid-back lifestyle.

Until a frantic 911 call sparks local police to action.

He said a response or the steering.

Is he breathing?

Investigators zero in on a lone stranger.

They get with a forensic artist and develop a sketch.

It was a eureka moment.

And a closer look at motive leads to unexpected revelations.

She knew a relationship was rocky, that it was not a good relationship.

It was starting to come to a head.

She was not going to be able to survive.

She was getting desperate and even had an insurance policy.

Let the desk at the motels just stay now.

Most people who think they're really smart and that they're going to commit the perfect homicide,

they don't.

Sargent, Texas in Matagorda County sits on the Gulf of Mexico about 70 miles southwest of Galveston.

Matagorda County is rural.

It also is coastal.

So we have a lot of hunters, fishermen, retired folks who live here.

Sargent is a little bedroom community.

If you walk in there, people will want to know, who are you and what are you doing here?

They know each other.

May 17th, 2009, 8:56 p.m.

An otherwise quiet Sunday evening in Sargent is shattered by an urgent 911 call.

911,

I need a place.

I get an ambulance.

Okay, what's going on?

And somebody, what, ma'am?

The caller, 59-year-old Kathy Grigsby, says she just found her husband, 72-year-old Jack Grigsby, unresponsive.

Where's your husband right now?

He says every flat earth turned over his floor.

Is he breathing?

Just punches thinking of himself.

Does it look like he may have possibly hurt himself?

I don't know.

I don't know.

I don't know.

Do you think somebody hurt him?

Moments later, first responders arrive at the home on Old Caney Road and meet Kathy.

It was a two-story house.

She was crying or going along quite a bit with some hysteria.

She kept saying, Jack is dead.

Jack's dead.

When they walked in, Mr.

Grigsby was lying on the floor.

Blood pooled around his head.

The recliner that he had been sitting in was overturned.

There was no sign of life or no possible chance to resuscitate or anything.

He has a spot of blood on his chest and then a pool of blood underneath his head, rather obvious some sort of head wound.

And that's when we discovered that he had a gunshot wound to his head.

At that time, then we knew that we either had a suicide or a homicide.

Back outside, Kathy Grigsby is inconsolable.

She was screaming that he was dead quite loudly.

She did, you know, break down.

She seemed truly, truly traumatized.

Investigators began to try to find out who he is, what his background is.

Jack was kind of loved by all the folks who knew him and didn't seem to have anyone that would have had any ill will towards him.

Jack Bransom Grigsby Jr.

was born in Houston, Texas in 1936.

He was the first son,

and he had an older sister, two years older than he was, and younger brother.

I came in at the very last.

He had plans to join the seminary when he got out of high school, but he went went into the service instead.

After honorably serving in the Army, Jack rejoined civilian life and began a new career in Dallas.

Jack was a very, very hard worker.

He worked as a salesman for several years for a paper company, and then he eventually got so good at it that he opened his own paper company.

Jack loved people and he entertained his customers whenever they would come to town.

Jack got married in 1961 and he and his wife had two boys.

He wanted to be there for his boys.

He took them on camping trips and stuff like that.

But after more than 20 years together, Jack and his wife ended their relationship in 1982.

They divorced eventually and went their separate ways.

In 1991, Jack crossed paths with Kathy Harris.

They met at a party at a friend's apartment

and found they had some things in common.

Kathy was born in 1949 in Bristol, Tennessee, but eventually moved to New Mexico, then Texas.

Kathy had been kind of a nomad.

She'd spent a lot of time in West Texas, became a bookkeeper, and ended up in the Dallas-Fort Worth area working at a Walmart mail center.

Kathy's first two marriages didn't work out, but they did produce a son and daughter.

Kathy more or less supported her family and you know supported her children.

The other great passion in Kathy's life was her service sorority, Epsilon Sigma Alpha.

She was the chapter president of our group.

We would just have fundraisers.

you know, it started out like bike sales, garage sales.

We would support and give to St.

Jude's.

That was our charity.

It was after Kathy's kids were grown up and on their own that she met Jack Grigsby.

Though he was 13 years her senior, Kathy was drawn to Jack's laid-back nature.

He was a quiet, peaceful person.

He never made waves.

He was never angry.

He was just a quiet, gentle man.

After six years together, they tied the knot in 1996.

And then Jack retired in 2001.

The couple sought a more peaceful life, leaving behind the hustle and bustle of Dallas for the quiet calm of Sargent less than five hours away.

He just moved down here to retire on the water to where he could fish every day and just a real laid-back lifestyle.

52-year-old Kathy wasn't quite ready for the life of a retiree,

so she got a job as a bookkeeper at the Salvation Army.

That's where we originally met.

Everybody was just crazy about her.

She was very cheerful, happy.

Always looking on the right side of things no matter what.

Kathy stayed active in her sorority and kept busy with work, but she missed the energy of the city.

I don't think she was happy when Jack moved her from Dallas.

She went from a popular place to a nowhere place.

They argued a lot.

After 10 years together, It was clear the age difference between 65-year-old Jack and 52-year-old Kathy had become a problem.

She lived a different life than him.

She was always wanting to be on the go.

She had a lot of sorority sisters that she would go to Dallas to meet.

She wanted more from him than what he was giving her.

She said they were really struggling and not getting along.

And she said, I really think that it's time that we just separate.

She had moved out and into an apartment that Jack was paying for and a car note that Jack was paying for.

She knew the divorce was imminent.

By 2009, Jack was in his 70s and his health began to decline, making the split even harder.

He had had a stroke, so one side of him, his arm and his leg, kind of drug.

Jack was ill.

She felt really sad.

I think think she struggled with, you know, their breakup.

June is when the divorce proceedings are supposed to take place.

The divorce would be final at that point.

Despite the impending divorce, Kathy often checked in on Jack when he felt ill.

By 2009, they were back in divorce court,

but they were still on friendly terms.

The couple seemed to be adjusting to this new chapter of life

until the devastating night when Kathy discovers Jack dead inside the home they once shared.

Kathy said she had just returned from Dallas and dropped her friends off and then come back to the house.

She had called him earlier in the week to see if he would watch her dog while she went out of town to a sorority convention.

Of course, he loved animals and he wasn't going to say no.

And he kept the dog.

After four days in Dallas, Kathy stopped by the house to pick up her dog.

When she got there, she said the door was unlocked and the lights were off and she discovered him on the floor.

Kathy says that lately Jack had been depressed.

There was some suggestion that he was in some poor health, didn't leave his house much any longer, and so there was certainly some possibility that it was a suicide.

A deputy escorts Kathy to the sheriff's department for a formal interview while authorities begin to process the scene for evidence.

Typically, if somebody were to shoot themselves, a gun falls very close proximity.

We'd remove the body to make sure the gun hadn't fallen inside the chair.

We didn't find a weapon at that time.

That's one we knew we were working a homicide.

Coming up, a theory takes shape.

They found some evidence in Mr.

Grigsby's journals and investigators seek a mysterious suspect.

This car kept circling, would pull up into Mr.

Grigsby's driveway and leave.

He just seemed, I don't know, you know somebody just AI.

night.

The homicide investigation for the death of Jack Grigsby is underway after his wife, Kathy, found him dead inside his home from a gunshot wound.

Whoever did it left something behind.

There was a shell casing found.

It was a nine millimeter casing.

A spent shell casing can give you lots of other leads.

It can be used to match a particular gun.

We didn't see nothing damaged on the door.

It was either forced open, kicked in, and none of the windows broke.

His wallet was in there.

It had quite a bit of cash in it.

It did not appear to anyone that it had been a robbery or burglary.

Either Jack let someone into his home or the front door was unlocked.

Maybe it was someone he knew because he appeared to be sitting in his chair when he was shot, so he was comfortable.

We have some knowledge of a timeline and a time frame of death based on the state of Rigor Mortis.

Now we had a mirror window of a couple hours that we were looking at.

Investigators look to his distressed wife, Kathy, for answers, and she pulls herself together to assist.

When I first seen Kathy, she was a little hysterical.

She became very quiet, low-key when we interviewed her.

She says they had the friendly relationship even though they're getting divorced.

Kathy says she dropped her dog off with Jack on Wednesday before driving to Dallas with two of her sorority sisters.

Dallas is about five-hour drive from Sardin, Texas, and she was there for a number of days, including Sunday.

She did provide officers with receipts that supported her alibi.

Investigators asked Kathy who else had access to the home.

She did bring up a individual's name of Royce Coody,

who had been doing some work or helping Jack remodel his house.

She just said that she didn't know a whole lot about him and then Jack had just previously met him.

She was just giving us the idea that there is somebody else out there that would have access to the house.

There was some indication that he had been to the house a number of times, but he certainly would have been someone that would have been welcome into the house.

So the police certainly weren't going to ignore that as a possibility.

Investigators then ask if Kathy owns a gun.

She said that she had a 9mm Aruger that she had bought from her boss where she works.

Her boss happened to have an extra handgun.

Kathy claimed to need the gun for personal protection.

There was a shell casing that was recovered at the scene, and the shell casing was a 9mm.

Investigators tell Kathy they will need her to turn over the weapon.

She agrees.

She signed a consent to search and she told them, you know, where the gun was located in her apartment and on a stand next to her bed.

Deputies accompany Kathy to her apartment.

When they went into her house and did the search, the weapon was not where it was kept.

She last seen her gun, I believe she said on Thursday before she left to go out town.

They began searching the other areas of the apartment just to make sure it wasn't misplaced.

And then she claimed that the weapon had been stolen.

There's no forced entry to her apartment.

She told them that nobody else had a key.

So then the only person who might otherwise have a key to her apartment obviously would then be the apartment managers or, of course, the maintenance man.

With no sign of a break-in, investigators believe it's plausible that someone with access to Kathy's home may have taken the gun.

Before investigators wrap up with Kathy, she also gives them Royce's number.

But when they call, it goes to voicemail.

So they don't discount the possibility that it's the maintenance man or Mr.

Cootie.

But by that point, the fact that now this gun is not there that she has said was there again

places her under more suspicion.

Despite their doubts, authorities continue trying to find Royce and ID the apartment maintenance man.

Meanwhile, they get the autopsy results.

The autopsy revealed a gunshot wound to the head caused death.

We were also able to identify a probable time of death.

Between the time he was killed and the time he was found, probably four or five hours.

So the murder took place on Sunday, after 1230.

The finding bolsters Kathy's alibi.

She and the ladies were in the process of driving home during the timeframe in which Jack would have been killed.

I think it would have been hard for her to leave from there without her friends and come down here and commit that crime and then go back before they would miss her.

Investigators head back to Jack's house, where crime technicians have been processing the home through the night, and they've made an important find, Jack's journal.

The final entry details a visit from handyman Royce Coody.

They found some evidence in Mr.

Grigsby's journals that indicated that Mr.

Coody had been there the day before Saturday.

Investigators learn that someone they've been wanting to talk to is asking to speak to them.

When they step outside the home, they find Royce Coody

himself.

Royce came down and he wanted to know what happened.

Mr.

Coody said that the last time he'd seen Mr.

Grigsby was the Friday before his death.

He'd done some repair work and he'd gone over to Mr.

Grigsby's house to clean some fish.

The police confronted him with that discrepancy.

You know, hey, we've caught you in a lie.

Now tell us the truth.

Royce Royce referred to some memory issues.

He said he was there on Friday for a different purpose and just forgot he'd been there on Saturday.

That's his story.

Officials ask Royce where he was during the timeframe the murder took place.

His story was on Sunday that he had got up with a friend and went fishing.

Investigators allow Royce to leave with the understanding that they'll be following up on his alibi.

His alibi was he was fishing with a friend.

Well, they talked to the friend.

The friend confirmed that.

Turns out he was not physically in the area.

He had an alibi witness that basically ruled him out.

A few hours later, just as officials are wrapping up, yet another man asks to speak with them.

They are approached by a man, Joe Zamora, who says, I think that I saw something that might be important.

Mr.

Zamora had related to them that he'd been fishing there the day before on Sunday, and in the later part of the morning, early part of the afternoon, that he had seen a fellow driving a car that kept showing up in that area.

He wasn't fishing.

He kept driving around, just, you know.

And I was like, what the hell?

There's almost no traffic out there.

So it was very unusual on a Sunday to see this car driving by the same location time and time again.

This car would pull up into Mr.

Griggs' driveway and leave.

What we have car with you is a Ford Tourist.

Joe says that afternoon, the car pulled into the driveway one last time.

The man driving the car got out and went up to the door of Jack's to knock on the door.

Shortly after, the same car pulled up next to Joe.

He stopped and asked me how the fish it was, and I told him that ain't no good.

When he talked to me,

I don't know, man.

He just seemed, he knew somebody just a night.

Kind of made me embarrassed.

This individual would not look him in the eye when he was talking to him.

He was 5'10, kind of scrundy looking, kind of looked like a biker.

We thought that was definitely a good hit.

We were getting a little closer, so we were closing in.

Coming up, a hunch and a sketch turn up a suspect.

He bragged to people about being in a biker gang, that he could be somebody who could get things done.

Two days into the investigation of Jack Grigsby's murder, a witness named Joe Zamora tells authorities he saw a mysterious man at Jack's home around the time of the killing.

Joe described the man as a white male, 40s to 50s, and and heavy thick mustache.

Kind of average height, average build, wearing a baseball cap and sunglasses.

Finding the man in the Ford Taurus becomes top priority.

This is a huge tip for us.

It is a big break for us to have this witness.

The activity that this person was doing did not seem to fit anything other than being involved in this homicide.

He was willing to get with a forensic artist and develop a sketch based upon his memory of what the individual looked like.

We did put out the information to the surrounding areas to be on the lookout for anything with this guy's possible description and the four taurus.

Although Jack's wife Kathy has an airtight alibi, There is a lingering loose end from her interview still nagging at investigators.

She had owned a weapon of the same caliber that was used to kill Jack Grigsby, her estranged husband.

Kathy told police that she had purchased a handgun from her boss at the Salvation Army.

Authorities questioned Kathy's boss about the gun.

He said, yeah, in fact, he did sell a 9mm to Kathy.

He even showed us a bill of sale.

that was dated in March 2009.

He had not only sold the the gun to Kathy, but he loaded it with 10 rounds of ammunition.

He had a box that he kept with the remaining 40 chills.

We compared it and it was the same manufacturer, 9mm,

that was found at the same...

That was a little shocking.

By that point, the police realize she could not have been the shooter, but they certainly believe that she's being deceptive.

Kathy's alibi is she was there at that sorority convention in Dallas.

This is not something that can be disputed.

With suspicions surrounding Kathy's involvement growing, detectives reach out to her for another interview, but they are surprised by her reaction.

They're trying to get her back down to the sheriff's office and she attorneys up.

Attorney Collis says, I'm representing her.

Don't talk to her.

After nine days of circulating the mystery man's face around Sargent, investigators haven't turned up a single lead.

So they try a new tack.

I remember thinking, what are the odds that somebody would stop and get gas?

Sargent is a very small community.

There was a Texaco.

Anybody that's interested in getting gas, they're going to go to that convenience store.

That one happens to have surveillance cameras.

Authorities review surveillance video from the day of Jack's murder.

What they found was a vehicle that had in just around in the noon hour and sometime after that had made two stops at the Texaco station.

There was a Ford Taurus and then they saw the individual come out.

He fit the general description from the sketch.

It was a eureka moment.

He called me he was very excited, Captain.

Captain, I got it.

The first time he came to the store, he bought sandwiches and then came back again and bought beer.

He uses a debit card which is described as a loan star card.

It's a card that is given out by local government for welfare and food stamps.

That card is traced to to a lady by the name of Suzanne Matz,

and she's in the Dallas area.

They were also able to get some information from the application for the Lone Star card.

That application included the name not only of Ms.

Motts, but also included the person that was living with her.

And she was in a relationship with Daniel Ray Harrison.

And they were able to pull driver's license photos of Ms.

Motts and Mr.

Harrison.

Daniel's photo seems to match the man in the video and the sketch.

Who's Daniel Harrison?

We started doing criminal history background on him to see what type of individual we're dealing with and what he may be capable of.

He had been in prison before and he had been out on parole.

Mostly drug history.

There's no reason to believe that Daniel Harrison actually knew Jack Grigsby, which led detectives to ask, did he have a history with Kathy?

On June 4th, 2009, two and a half weeks after the murder, investigators make the 400-plus mile drive north to Denison, Texas to pay a visit to Suzanne Matz and her boyfriend, Daniel Harrison.

We went to interview them.

They didn't even know we were coming.

There was a car sitting out front that appeared to be the same car as what they had seen on the Texco video.

So we got there.

Daniel Ray Harris was not there.

Susan Matz was there.

We told Suzanne that we were investigating a death, Jack Grisby.

That's when we found out that there was a connection.

She had known Kathy for several years.

Suzanne says she met Kathy eight years earlier in 2001 when they worked together at a Walmart mail order center.

She claimed that her relationship with Kathy was that they'd been friends.

Kathy did her taxes for every year, that they'd kept in touch.

Kathy often confided in her about her problems with Jack.

She knew that the relationship was rocky, that it was not a good relationship.

In fact, six years earlier, Kathy made a comment that stunned Suzanne.

In 2003, Kathy was looking to get Jack killed.

She asked Ms.

Motts, do you know of anybody that would kill Mr.

Grigsby?

And I think Susan Mott's response to that was, well, no, I don't.

Kathy pressed, wanting to know if maybe Suzanne's boyfriend Daniel might be able to help her.

Kathy had met him and she thought he was kind of a bad boy because he had a history of being in and out of prison.

He bragged to people about being in a biker gang, about having connections to violence, that he could be somebody who could get things done.

Kathy thought he may know somebody to actually kill Jack Fall.

Suzanne played it off as, I didn't think she was serious, like I didn't think she really meant it, type of deal.

She's pretty adamant that she doesn't know anything about the murder.

When we confronted her with the fact that her car had been used on the sergeant, she admitted that she had let Daniel take her car and drive it that day.

To her knowledge, Mr.

Harrison had used her vehicle for work purposes on that Sunday.

As investigators wrap up with Suzanne, Daniel Harrison returns home.

He agrees to go to a nearby sheriff station for questioning.

I started talking to Daniel.

I said, did you know about Jack being murdered?

He said, no, I didn't know anything about him.

I showed him a copy of the otter sketch, and I could tell that it kind of shocked him.

And I said, well, Daniel, it looks a whole lot like you to me.

I said, now,

just help me understand this.

You say that you were not involved in this,

but how do you think we found you?

Nobody knows you down there.

You're 450 miles away.

How did I find you?

Coming up, Daniel tells a harrowing tale.

He knows she's tried to poison him.

She tried to rattle me to it.

And a potential motive emerges.

Each of them would have received 50% of the proceeds upon his death.

Texas investigators are preparing to transport suspect Daniel Ray Harrison for questioning in the murder of Jack Grigsby.

Under the law, we can lie to a suspect to get him to talk.

We can't fabricate evidence.

So when I was talking to Daniel Ray Harrison in my vehicle, I led him to believe that Kathy Grigsby had been the one who led us to him.

By the time they reach the station, Daniel is feeling the heat.

Can I go to sleep?

Just wake up me in an all-bad dream.

I wish that was the case, but it's just not going to be the case.

I said, well, we have an eyewitness that saw you there.

And I showed him a copy of the auto sketch McGimm.

I don't look like me.

That's crazy.

Oh, he picked you up.

Your part of the bargain is to fully cooperate.

So if I don't cooperate in now, it's just who wouldn't get mine.

Well, but you have to tell me the whole story.

So what do you want to do?

He thought that Kathy had already spilled the beans on him, and he was just ready to give it up and move on.

She wanted to do this a long time ago.

You know, she started to poison him 50 times, right?

Daniel says Kathy had actually tried to poison him with antifreeze in his coffee or something.

And it did cause some real failures.

He got sick from it.

Though there is no way to prove it, the alleged poisoning might explain Jack's decline in health.

Daniel says when it didn't kill him, that's when Kathy looked for help.

Daniel Ray Harrison and Kathy Grisby first met and talked about killing Jack Grisby in 2003.

He turned it down

and didn't pursue it any further.

He says he had no contact with Kathy until March of 2009, when Suzanne hired Kathy to do their taxes.

At that time, Daniel claims Kathy once again brought up killing her husband.

Yeah, she tried to pay me.

The prize moment was 10 grams.

Mr.

Grigsby had a life insurance policy of $200,000.

She and Jack Grigsby's son were 50%

beneficiaries.

And that's how she would pay him, letting him know that if I get the $100,000, I'll give you $10,000 for killing Jack.

He says, the first time she approached me, I was not interested.

But Suzanne and I are on hard time and we needed money.

So when she approached me again, I said yes, that I would do it.

Kathy allegedly explained they were under a deadline.

June is when the divorce proceedings are supposed to take place.

She would no longer be a beneficiary of the insurance policy, so she would have wanted this to take place before that divorce proceeding took place.

Daniel says two weeks later, he met Kathy in person to discuss the details.

He claims Kathy proposed he kill Jack while she was at an upcoming sorority convention in Dallas.

She's going to be in Dallas at the convention.

Where he lives is a little bit north of Dallas.

He was to go to the hotel where she was staying.

She told Daniel Roy Harrison that I have a gun.

It's a nine millimeter.

She told me the gun wasn't missing her name yet.

She had the weapon at her house.

She had it loaded.

She was prepared.

She went to a local Walmart and had a copy of a key to her apartment made.

She took me a key to the apartment and then the desk at the motel she's staying at.

He picked it up around 3.30 a Sunday morning.

Okay, Danny, so you picked up the gun on the way out there to the house.

And when you got out the house, was he there?

Nope.

How many times do you go by the house for you?

Too many.

That's obvious.

What time did he actually get there?

12.30.

Posing as a stranger looking for a good fishing spot, Daniel approached Jack's home.

I thought it was already coming.

And what do you talk about?

Fishing.

So

after you talked a little bit, what happened?

Daniel asked him, could he go inside and use the restaurant?

So they wind up going inside.

He went to the restroom and then when he came back, he had the nine-miller pistol.

Jack was sitting in his lounge chair with his back to him.

I told Cochrane on the back of the head with the pistol turned around so that the girl was hanging.

And then he proceeded to shoot him directly in the head.

Headshot execution stopped.

Daniel left the house and spoke with Joe Zamora to feel out if he had heard the shot.

Then he called Kathy.

Right.

So what did you tell her?

Done.

And from there,

it's done.

And her response was, how was my dog?

Pretty cold.

You got rid of the gun.

Tell me about the gun.

I rid of the barrel and I rid the pistol.

At Lake Texoma, you said

he went back home to Suzanne, who was none the wiser.

You swear to me

that Suzanne had nothing to do with it.

After I got a signed confession from Danuer Harrison on the murder, they got a problem cause affidavit and arrest warrant for Kathy Grisby.

They went to the Salvation Army and arrested her there on site.

In front of everyone, I was really shocked.

Kathy refuses to give a statement.

But when authorities search her purse, her habit of keeping receipts comes back to haunt her.

She had a receipt for the key being made at Walmart, which ultimately we knew was the key that she gave to Daniel Harrison to gain access to get the gun to commit the murder.

So everything started coming together at that point.

She planned this and he carried it out.

Coming up, a hard truth comes out at trial.

The irony of the whole thing is that she wouldn't have got a dime.

19 days after Jack Grigsby was found shot dead in his home, investigators work with prosecutors to build their case against his wife, Kathy Grigsby.

They request surveillance video from the Dallas Hotel where Kathy stayed during the convention.

The videos pretty clearly show that she left the key at the front lobby, at the front desk, instructed them who to give it to.

And that Harrison at 3.30 in the morning came and picked it up and showed his ID.

After we got the confession of Daniel Ray Harrison and video from the hotel, I felt very confident that we were making a very strong case against Kathy Grigsby for the murder of Jack Grigsby.

Authorities want to offer Daniel Harrison a deal, a murder charge, and 40 years in prison if he cooperates.

Daniel accepted a plea deal and agreed to testify against Kathy.

Kathy Grigsby's murder trial begins on October 25th, 2010.

Prosecutors argue that Kathy was motivated by one thing and one thing only, money.

What I think finally made Kathy snap was the fact that the divorce was starting to come to a head and that Jack was cutting her off financially.

The credit cards have been run up.

He'd finally cut her off the credit cards.

He also planned to stop paying for her apartment and car loan.

She was not going to be able to survive without his help.

Knowing she was going to be cut off soon, prosecutors believe Kathy became desperate to change her fate.

At trial, Daniel Harrison said that Kathy had told him that she tried herself to kill Jack through poisoning him.

We were never able to really confirm that that had happened and it lined up with what his health issues were.

She was getting desperate and she knew that Jack had an insurance policy.

In a surprise twist, prosecutors reveal that Jack had already taken action to make sure Kathy wouldn't get that money.

Jack had changed the beneficiary on his life insurance policy.

Kathy was no longer a beneficiary.

She wasn't in the will.

She wasn't going to get the house.

She wasn't going to get the money.

The irony of the whole thing is that she wouldn't have got a dime.

Kathy's confessed co-conspirator, Daniel Harrison, testifies against her.

But Kathy's defense attempts to turn the prosecution's star witness into a liability.

Daniel Harrison is a criminal who confessed to being the person who shot Jack Grigsby.

Kathy's never been in trouble.

You know, she's a churchgoer.

She's not somebody who would ever commit this kind of crime.

They basically

attempted to show Mr.

Harrison was a liar.

The jury deliberates for just over an hour before returning a verdict.

The jury does find her guilty of capital murder, and capital murder is an automatic life sentence in Texas.

I think the system worked.

She'll die in prison.

Most people who think they're really smart and that they're going to commit the perfect homicide, they don't.

I feel bad for Jack.

I feel bad for his family.

I'm sure he wanted to live one more day to say, I love you to his kids.

My brother is up there in heaven with my other brother, and they've gone to the big fishing hole in the sky.

Having a ball.

Kathy Grigsby is serving a life sentence.

Daniel Harrison was sentenced to 40 years.

He will be eligible for parole in June 2029.

Suzanne Matz was never charged.
