He Was Executed on His Own Doorstep—Then Police Uncovered a Horrifying Plot… Crime Documentary
July 12th, 2024. Utah, a gated community in a quiet suburban neighborhood, tucked behind tall security fences where law enforcement is usually called for nothing more serious than complaints about loud music or a neighbor’s dog barking too long on the front lawn. But on this summer evening, the calm was shattered by a series of deafening gunshots.
A shaken resident immediately called emergency services. When deputies entered the house, they were met with a disturbing scene. Lying on the entryway floor was the bloodcovered body of 42-year-old Matthew Restelli. Standing nearby were two people, the homeowner, Tracy Grist, Matthew’s mother-in-law, and her son, Kevin Ellis, Matthew’s brother-in-law.
What stood out immediately was how calm they appeared. No panic, no shaking hands. They confidently told the deputies that what had happened was a harsh but completely justified act of self-defense. According to Tracy and Kevin, Matthew had suddenly forced his way into the house in the middle of the night.
They claimed he was carrying a knife and intended to harm everyone inside. Kevin said he grabbed a firearm to protect himself and his mother, then opened fire to stop the threat.

At first, the story Tracy and Kevin told sounded believable. An angry relative, a family conflict, a desperate fight to protect innocent lives.
But experienced investigators saw something completely different the moment they stepped inside. Within minutes of examining the scene, Tracy and Kevin’s official version of events was already beginning to fall apart. The deputies noticed details that simply didn’t fit the picture of a violent home invasion. First, they looked down at the front doorway.
Do you know what this supposedly enraged man who allegedly came there to attack the family did before entering? He carefully took off his hiking sandals and neatly placed them against the wall so he wouldn’t track dirt through his mother-in-law’s house. Think about that for a second. How often does someone who’s supposedly about to carry out an attack stop to worry about keeping someone else’s carpet clean while running on pure adrenaline? Personally, I’ve never come across a contradiction quite like that. And the
strange details didn’t stop there. Investigators stepped outside to examine Matthew’s vehicle. It was an old car with a serious mechanical issue. The engine leaked oil badly. Underneath the engine, resting on the spotless driveway, was a carefully positioned piece of cardboard. Investigators would later learn that Matthew had asked his wife ahead of time to put those sheets out for him.
When he arrived, he parked with incredible precision so the leaking oil wouldn’t leave stains on Tracy’s driveway, even in what would become the final minutes of his life. That was something he had taken the time to think about. You have to admit those tiny everyday details completely change the entire picture. They point to one conclusion.
Matthew came there with peaceful intentions. Someone who worries about keeping the floors and driveway clean isn’t showing up expecting to start a violent confrontation. The deputies exchange glances. They’re already starting to realize that no one inside that house was defending themselves from an attack. Matthew Restelli was lured into a trap and shot the moment he reached the front door.
This wasn’t a split-second act of self-defense. It was a carefully planned setup. But proving that and understanding how a devoted father became the target of his own family would require investigators to rewind the story. To find the answer, we have to leave Utah and head to neighboring California, where we’ll take a closer look at the inside of a deeply toxic marriage.
One where greed, deception, and an obsession with control eventually led to irreversible consequences. To understand what motivated this shocking crime, we need to go back several months to the beginning of 2024 and travel from Utah to California. Our story shifts to the tiny community of Awanga, home to fewer than a thousand residents.
Our focus is a secluded house sitting at the edge of a dense forest. The nearest neighbors live more than a mile away, and it’s perfectly normal to see wild turkeys and even mountain lions wandering through the property. That’s where the Restellis lived. Matt and Catherine, whom relatives simply called Kate.
Together, they were raising three sons. Matt’s oldest son from a previous relationship with whom he regularly spent time riding mountain bike trails along with the couple’s two younger sons. Matt was deeply involved in mountain biking, competed at the national level, and by every account was the kind of dad who centered his life around his family.
From the outside, it looked like the perfect life. Inside the house, though, constant arguments had become part of the daily routine. Both Matt and Catherine were incredibly stubborn, and disagreements could start over almost anything. But there was one major difference between them. Matt was doing everything he could to save the marriage and keep the family together.
Catherine, on the other hand, had already been involved in a romantic relationship with another man for more than a year. At the same time, Kate was playing a very calculated double game. She stayed in regular contact with her relatives back in Utah and gradually built an image of Matt as an unstable and aggressive man.
She secretly recorded their arguments on her phone, but there was a pattern. She would provoke the confrontation herself, then send her family only the clips where Matt could be heard yelling, leaving out everything that had happened beforehand. Over time, her relatives became so convinced that he was the problem that in their family group chats, they gave him humiliating nicknames and even replaced his contact icon with the poop emoji.
As I was going through the investigative files, one detail immediately caught my attention. Why spend so much time and energy turning your own family against your husband if you’re already planning to leave him anyway? The answer starts to emerge inside the office of a California divorce attorney, where Catherine shows up in early 2024.
That’s where Catherine receives a harsh legal reality check. California law is very clear on this. When parents divorce, custody is generally split 50/50. The attorney tells Catherine directly that she has no legal right to take her sons and moved to Utah to live with her mother. There is only one major exception.
She would have to convince the court that there was credible evidence of ongoing physical abuse. That’s exactly why she needed to be seen as the frightened victim. The financial picture was even worse. She learned that the large piece of property and the secluded house in the woods didn’t belong to her or Matt at all. They belonged to Matt’s parents.
Catherine didn’t have a job, had no personal savings, and was living almost entirely on money her mother regularly sent her. A legal divorce would leave her with nothing. She wouldn’t receive the house. She wouldn’t receive sole custody. and she wouldn’t be allowed to leave California with her sons. Realizing that the legal route wasn’t going to give her what she wanted, Kate turned to much dirtier tactics.
She waited until Matt left on a trip, then quietly hired people to help her. Methodically, Catherine emptied the house, packing up furniture and anything valuable into a rented storage unit. After that, she put their two younger sons into a rental car paid for by her mother and left California without saying a word.
Matt came home to an empty house. His belongings were gone. He had been cut off from his sons, and he had no idea where his family had gone. He sat there alone inside those bare walls, not realizing that his wife’s secret escape was only the first step in a carefully planned chain of events. While Matt was trying to process the collapse of his life inside that empty California home more than 600 m away in Utah, a completely different plan was already taking shape.
Catherine arrived safely at her mother Tracy Gri’s house with the boys. And inside that house, what had started as a divorce dispute began turning into preparations for a calculated crime. To understand just how extreme this situation became, you have to take a closer look at Tracy herself. By nearly every account, she had an incredibly difficult personality.
Even her own family openly described her as someone who deeply resented men. Because of painful experiences in her past, she looked down on almost every man her daughters had ever been involved with. But her hatred toward Matt stood out even among the rest. She made no effort to hide it.
Just a few months earlier, she had already called her son-in-law and made direct threats. When Catherine later tried to smooth things over and asked her mother to apologize, Tracy answered with a line that said everything about her mindset. I’m not apologizing to that coward. I’d rather drive 9 hours and choke him myself.
Now that her daughter was back under her roof, Tracy took control and she left behind an enormous digital trail, she became intensely focused on one specific criminal case. The prosecution of Donna Aden, the American woman accused of arranging the contract killing of her daughter’s former husband. Catherine’s mother, read article after article about the nationally known case.
Then her online searches shifted to Utah’s firearm laws, specifically when deadly force could legally be used. Not long afterward, she also began looking up local cemeteries throughout the area. Do you know what may be the most shocking part of this story? It’s not even the plan itself. It’s the absolute confidence these people seem to have that they would never be caught.
In an era when nearly every online search leaves a digital footprint, they acted as if no one would ever trace it back to them. Around that same time, Tracy ordered a rare tactical military-style knife online, buying what investigators would later believe was a key prop for a future self-defense narrative.
But Tracy had no intention of carrying out the plan herself. She needed someone else to do it. And the perfect pawn was sitting in the next room. Catherine’s own brother, Kevin Ellis. 30-year-old Kevin, didn’t have a job. He had been struggling with severe clinical depression and relied almost entirely on financial support from his mother, occasionally asking her for money to support his one real hobby, playing pool.
Kevin felt like a burden. During one of the lowest points in his life, he openly admitted to his family that he had been experiencing thoughts of self harm. Instead of encouraging him to seek immediate professional help, Tracy saw his emotional vulnerability as something she could use.
In a conversation with Catherine, she coldly suggested that if Kevin already believed his own future didn’t matter, he should first deal with his brother-in-law. From that point on, the two women began systematically shaping Kevin’s view of reality. Day after day, they filled his head with terrifying stories, convincing him that Matt was an unstable and dangerous man who would soon come to Utah and attack the family.
A depressed, insecure man was gradually being transformed into someone who believed he had to become the family’s protector. But to make the ambush work, they needed to know exactly where Matt was at all times. A few days before leaving California, Catherine quietly slipped an Apple Air Tag, a small location tracking device, into the trash compartment inside Matt’s vehicle.
After arriving in Utah, she shared access to the tracker’s location with the rest of the family. Before long, they had turned that tracking app into something resembling a twisted reality show. On the digital map, they even replaced the standard vehicle icon with a poop emoji. Then they repeatedly refreshed the app, watching in real time every mile drove, completely unaware that his movements were being tracked.
The mechanism was now in motion. The trap was ready. Everyone knew their role. All the conspirators needed now was one final step. They had to convince their target to come to them on his own. Then July 12th, 2024 arrived. Catherine made the next and most important move in her plan.
She called the husband she had left behind. Her tone was completely different from anything Matt had heard in months. The accusations were gone. The emotional distance had disappeared. Instead, she told him she still loved him. She said she had made a terrible mistake, wanted to make things right, and hoped they could save their marriage.
There was just one small obstacle standing in the way of their reunion. Catherine told Matt she had badly twisted her ankle. She claimed she physically couldn’t press the pedals and wasn’t able to drive the boys back to California. Instead, she asked him to come to Utah and pick them up. Matt was of course thrilled.
He was ready to leave that very minute. But he suggested something completely reasonable. He offered to buy her a plane ticket or rent a dependable vehicle. The reason was simple. His old car was in terrible condition. The engine leaked badly and driving nearly 600 m across multiple states in that vehicle carried a real risk of breaking down somewhere in the middle of the highway.
That’s when Catherine became strangely stubborn. She insisted that Matt come only in his old car. No flights, no rental car. Do you see why she was so determined? If Matt switched to another vehicle, the hidden Air Tag would be left behind in California. The conspirators would instantly lose track of his location.
They’d have no way to monitor his movements, and the carefully planned timing of everything would fall apart. Eventually, Matt gave in and agreed to those unusual conditions. A nearly 10-hour drive lay ahead of him. Throughout the entire trip, the two of them stayed in constant contact. Catherine kept lowering his guard.
She sent one affectionate message after another, telling him how much she missed him and how excited she was for him to arrive. Matt answered with the same warmth. He was completely disarmed. He genuinely believed he was driving to bring his family home. His mind was so far removed from anything suspicious that the only thing truly worrying him during the drive was his leaking engine.
He even texted Catherine himself, asking her to lay several sheets of cardboard on the driveway outside Tracy’s house before he arrived. He simply didn’t want to stain someone else’s property with leaking oil. While Matt kept putting miles behind him, preparations for the final act were already underway inside Tracy Gri’s house.
Catherine went upstairs to the bedroom where her two younger sons were sleeping. Concerned that they might wake up because of the noise and wandered downstairs at the worst possible moment, she gave them melatonin. The sleep aid would help make sure they stayed asleep until morning. At the same time, downstairs on the first floor, Tracy was preparing the scene.
She carefully cleared all of the toys scattered around the living room so no one would accidentally trip over them in the dark. Then she picked up a heavy blanket and neatly draped it over an expensive couch. Just think about the level of planning investigators say this reflects. According to the prosecution, they were preparing for someone to be shot.
Yet at the same time, they were worried that blood might stain the furniture upholstery. Everything was in place. The preparations were finished. Everyone knew their role. Kevin took his position by the front door. To boost his confidence and according to investigators, silence any remaining hesitation. He used cocaine.
A loaded handgun was already secured to his waistband. The bait had worked perfectly. The target was driving straight into the trap on his own. At 10:06 p.m., Matt pulled up to the house in Utah. The tracking device hidden in his vehicle reported his exact location, and the people waiting inside knew immediately he had arrived.
Matt carefully pulled into the driveway, lining up his wheels directly over the pieces of cardboard he had asked Catherine to put there. He had come to pick up his family full of hope, genuinely believing they were about to reunite and begin the long drive back to California together. Next, he entered the gate code on the keypad.
Those were the numbers Catherine had sent him earlier. She had also specifically instructed him to come inside without knocking so he wouldn’t wake Tracy, who was supposedly asleep. Matt turned the door knob and stepped across the threshold. The moment he walked inside and straightened up, Kevin opened fire.
Caught completely off guard, unarmed, and in total shock, Matt instantly realized he had walked into an ambush. He desperately tried to turn around and run back outside. He never got the chance. According to investigators, most of the rounds struck him in the back. He collapsed face down onto the entryway floor, coming to rest on the rug directly in front of the same couch Tracy had carefully covered with a heavy blanket beforehand.
At that very moment, upstairs, Matt’s own sons remained asleep. The melatonin Catherine had given them earlier had done exactly what it was intended to do. They never woke up despite the sound of gunfire inside the house. Now, ask yourself a simple question. How do people usually behave after a genuine unplanned act of self-defense? They’re overwhelmed with adrenaline.
They call emergency services immediately. They panic. They try to help. They do whatever they can to save the injured person or at the very least try to stop the bleeding. But that’s not what happened here. Kevin, Tracy, and Catherine didn’t call for medical help after 1 minute or 5 minutes.
According to prosecutors, they stood over their wounded relative for nine long minutes, simply waiting for his heart to stop. The call to emergency services happened only because of one unexpected interruption. A neighbor who had heard the loud gunshots in the otherwise quiet neighborhood sent Tracy a text asking if everything was okay. Only after realizing the gunfire had attracted attention and that it could no longer be hidden did Tracy finally pick up the phone.
And during that waiting period, investigators say the most important piece of staging took place. Tracy retrieved the tactical knife she had specifically purchased online just days earlier and placed it into Matt’s hand. The idea, according to the prosecution, was as simple as it was calculated. portray Matt as an unstable aggressor and frame the shooting as an act of necessary self-defense.
But real forensic science is a lot less forgiving than the kind of scenarios people imagine after watching crime dramas. The experts who examined the evidence dismantled the entire staging almost immediately. Take a look at how implausible this looked from a forensic standpoint. Tracy placed the knife into Matt’s right hand.
The problem? Matt had been strongly left-handed his entire life. In a high stress situation, people instinctively used their dominant hand. And there was another problem. The knife itself had been positioned with the blade facing back toward Matt’s body. From a physiological standpoint, that’s simply not a natural grip for someone preparing to attack.
But the strongest evidence came from the medical examiner. One of Kevin’s bullets passed completely through Matt’s right wrist. The muscles and tendons had been critically damaged within the first moments of the shooting. With an injury like that, it’s physically impossible to maintain a firm grip on a heavy object. If Matt had actually entered the house holding that knife in his right hand, the weapon would have hit the floor almost instantly because of the trauma and involuntary muscle response.
Investigators documented every one of those details at the scene. What had been planned as a carefully constructed self-defense narrative quickly unraveled, leaving investigators with what they believed was clear evidence of a deliberate crime. While crime scene investigators were downstairs documenting Matt’s injured wrist, Catherine was upstairs.
The man she had spent 8 years married to had just been killed. you’d expect shock or grief. Instead, Catherine calmly opened Discord and started a video call with a close friend. She pointed her phone’s camera toward the entryway floor and gave her friend a tour. Look, this is where he died. Her friend was reportedly speechless.
Then, in the background, Tracy made a comment that only made the moment even more disturbing. She said that if she had known her friend enjoyed dark or morbid things, she would have taken pictures of the body. When I read those investigative reports, I couldn’t believe the level of indifference they described. The very next day, while Matt’s body was still at the medical examiner’s office, Catherine was getting ready to go on a date with another man.
Investigators didn’t find searches for funeral arrangements in her browser history. Instead, they found searches like, “How do you get rid of a hickey fast?” and “When should you tell a guy you love him?” It appears they genuinely believed law enforcement would treat the case as nothing more than Kevin using excessive force in self-defense and that the story would end there.
Instead, their digital trail became the foundation of the case against them. recovered text messages, the Air Tag location history, cashed records documenting the purchase of the tactical knife. The illusion of the perfect plan collapsed piece by piece. In November 2024, Catherine and Tracy were both arrested. Once they were behind bars, family loyalty disappeared almost immediately.
Catherine reached an agreement with prosecutors and turned on her own brother, the same Kevin she had helped manipulate with lies and convinced to pull the trigger. She did it in hopes of receiving a lighter sentence. Kevin was convicted in connection with the crime and sentenced to prison. Tracy’s case was separated and scheduled for its own trial.
The ending of this story is hard to ignore. During the sentencing hearing, the judge publicly stated that Catherine had never truly acted in the best interests of her sons and had instead used them as tools of manipulation. She received a life sentence with the possibility of requesting parole after serving 6 years. But perhaps the most significant part of the sentence was something else.
The court imposed an extraordinary restriction. Catherine was permanently prohibited from having any contact with her sons, not even through third parties. Complete isolation. The boys were placed in the care of Matt’s brother. Today, they’re growing up in a safe environment, surrounded by family, including their grandmother, who suffered an unimaginable loss when she lost her son.
Catherine wanted total control. She wanted the assets. She wanted sole authority and she was willing to ignore the law to get it. In the end, her greed cost her everything. Matt paid with his life because he trusted his own family without question. But the truth about what happened to him never stayed hidden beneath that rug in.
