How the State Is Prosecuting Tracey Grist Without Kate Restelli

The neighbor called 911 before Tracey Grist did.

Caitlyn Laney took the stand in Provo this morning. She lives in the unit next door to Grist's townhome in American Fork. Shared wall. Gated community. On the night of July 12, 2024, Caitlyn was watching a movie with her husband and kids when she heard six to eight loud bangs one wall over. She looked out her window. She saw a truck she did not recognize. She texted Tracey Grist to ask if everything was okay. No answer. So she picked up her phone and called 911.

The timestamp on her call, which is now in evidence as the state's Exhibit 36, is 22:09:42. One minute after the shots. Tracey Grist called 911 eight minutes after the shots. Those two timestamps are now benchmarks the jury has in evidence before anyone has even said the word "conspiracy" on the witness stand.

Then the state played the text messages Grist sent the neighbor the next morning. At 6:58 a.m. on July 13, 2024, less than nine hours after a man bled out on her floor, Grist texted Caitlyn: "He had a knife. And my son Kevin shot him." That text was not a response to a question. The neighbor had asked "Was it your son-in-law?" and Grist had answered yes. Then, unprompted, Grist offered the explanation. And the words she chose almost exactly match what her son Kevin told police at the scene.

Later that afternoon, Caitlyn went over to Grist's house in person. Grist walked her through the story: Matt was erratic. He had a knife. Kevin shot him. And then Grist showed Caitlyn the gun case. Her gun. From her garage. Kevin got it, she said, the evening Matt arrived.

None of that came from Kate Restelli.

The Kate Problem

Here is what we need to understand about what happened yesterday.

Kate Restelli, Grist's daughter, is the state's star witness. She has already pleaded guilty to murder, conspiracy to commit murder, and criminal discharge of a firearm. She is serving time in Utah prison. And her testimony is the centerpiece of the state's conspiracy theory against her mother.

Kate took the stand Tuesday. Direct examination delivered the full conspiracy timeline in the state's preferred frame. Her mother said "we can have him come out and shoot him and act like self-defense." Her mother showed her the knife wrapped in a rubber glove 2 to 3 days before the killing. Her mother scripted her texts to Matt. When Kate tried to back out, her mother said "I don't care. I'm doing it anyway." That last line is going to be in the prosecution's closing argument.

Then came cross. And Facemire opened three wounds in Kate's credibility that the state is going to be living with for the rest of this trial.

First, Kate's own proffer letter. Defense Exhibit 1. Dated June 6, 2025. Written by Kate's attorney as part of her plea negotiations. That letter describes Grist's involvement as passing comments, not any concerted effort where Kate, Tracey, and Kevin would meet to discuss a plan. Kate's words. Through Kate's lawyer. On the record. Contradicting what she said on direct.

Second, the overnight memory shift at Kevin's trial. Kate testified in January that she had no interaction with Kevin between 3 p.m. and 10 p.m. on the day of the killing. She slept on it. The next morning she came back with a new story about a planning meeting on the lawn. The defense is going to hammer that pattern. Her memory keeps conforming to what the prosecution needs.

Third, the Enterprise memory gap. Kate did not remember telling Kevin about the failed car rental until she was played the audio at his trial. At Grist's trial she testified as if she had always remembered it.

Add that to 18 years of daily marijuana use, an affair during the marriage, a domestic violence arrest against Matt that Kate herself admitted to, and a plea deal that builds her parole eligibility on the conspiracy testimony, and you have a witness with a serious credibility problem. Not an unbelievable witness. A compromised one.

The state knows.

The Four-Phase Theory

Prosecutor Dean Watabe laid out a four-phase conspiracy in his opening statement. Get Matt to Utah. Get him inside the house. Surprise and shoot him. Cover it up. He said in opening that Grist was the one person who wouldn't stop. Both Kate and Kevin tried to talk her out of it. She said I don't care, I'm doing it anyway.

That sentence only exists in Kate's testimony. It is Kate's word against a dead man, a convicted brother, and a mother charged with his murder. The whole closing argument is built on that line.

But here is what the state has also done, quietly, in the first two days of trial. They are building a parallel case that does not need that sentence. They are getting pieces of the four-phase theory into evidence through witnesses who have no plea deal, no prison jumpsuit, and no proffer problem.

Phase one, getting Matt to Utah. The digital evidence will carry this. AirTag tracking data. Phone records. The shared Facebook chat where Kevin, Rachel, Teralyn, and Tracey all had access to Matt's location as he drove across the desert. Kate's testimony describes it. The data itself does not need her.

Phase two, getting him inside the house. The phone calls between Kate and Matt, already played for the jury on direct, are in evidence. Matt's voice is now in the courtroom. The jury has heard him excited to see his kids. That was Kate's direct testimony authenticating, but the recordings themselves will stand on their own at closing.

Phase three, the shooting. This is where the detective testimony is coming. The knife positioning. The wrong hand. The backward blade. The bullet wound in the same arm. The bloodstains consistent with the arm being moved after death. A medical examiner will testify to the physical evidence. The detective will walk the jury through what the scene did not support. None of that requires Kate.

Phase four, the cover-up. This is today. Caitlyn Laney just put the first piece in the record. The 8-minute 911 delay. The morning-after text matching what Kevin told police. The gun story Grist told her neighbor before any investigator had talked to her. The next detective who testifies will add the search history. The "it's happening" meme search at 2:13 p.m. on July 12, made by Tracey Grist while she waited for Kevin at sushi. The Donna Adelson searches. The "how to get my passport fast" search.

All of that exists independent of Kate.

What the Defense Is Building

Facemire has not told us what the defense story is. Yet. His opening was notably light on specifics. He did not explain the texts, the searches, the tracking, or the knife. He called it the messiest conspiracy ever. He said law enforcement found a narrative and stuck with it. He pointed at Kevin Ellis being convicted and at uncharged family members still walking around free. One guy murdered a guy was the line.

What Facemire has been building is not a theory of what happened. It is a theory about the credibility of the evidence. And his best asset in that theory is Kate Restelli's own proffer. That is the structural piece. If the state's conspiracy case rests on a witness whose own prior statement says there was no concerted effort, the defense has a real argument that the state overcharged. Add to that the Ellis conspiracy acquittal. Twelve people heard substantially similar evidence in January and could not agree that the shooter was part of a conspiracy.

That is why he did not cross-examine Caitlyn Laney on the text messages, the 911 timing, or the gun story. He left those alone. He asked about memory and moved on. Because his case is not won on Caitlyn. His case is won on the conspiracy charge specifically, and Caitlyn only goes to cover-up and consciousness of guilt. Those hurt. They do not prove the agreement.

What We Are Actually Watching

Here is what I keep coming back to.

This trial is not a question of whether Tracey Grist did something wrong. The digital evidence alone, if it comes in the way the state has previewed it, establishes that she was deeply involved in the aftermath of her son-in-law's death and probably in the planning. The question the jury has to answer is narrower and harder. Did she enter an agreement with Kate and Kevin to commit murder, and did she intend for that murder to happen?

Under Utah law, that requires an agreement. Not just bad texts. Not just morbid searches. Not just a delayed 911 call. Not even just planting a knife. An agreement. A concerted effort. The very thing Kate's own proffer says did not exist in the way the state is now describing.

That is the case. The state has to prove the architect when the shooter has already been acquitted of conspiring. And the one witness who would put the architect in the room cannot do it without the jury wondering why her story keeps getting better.

So the state is doing what good prosecutors do when they have a witness problem. They are building the case through everything that is not the witness. Civilian testimony. Digital evidence. Forensic extractions. The defendant's own words, told to people she did not think were listening.

Caitlyn Laney was the first piece of that work. Brent Laney will be next. Then Aurora France. Then the detective. Then the digital evidence. Each one puts another layer of the case into the record that does not depend on Kate.

Whether it will be enough depends on what the jury decides an agreement is. That is the whole trial. And it is a closer call than the state's opening made it sound.

We are watching a prosecution that knows its star witness is wounded. That is not a weakness in their case. That is a choice. A good one. And we should be paying attention to how they make it.
