Teen Kills and Dismembers Friend Inside Father’s Trailer: The Chilling Case of Nick Vetishnik

On May 26, 2021, in Salt Lake City, Utah, police were called to a quiet residential neighborhood after a father made a horrifying discovery on his own property.

Jeremy Aguilar had been looking for his teenage son, Rowdy. At first, he was only worried that Rowdy had skipped work, stolen alcohol, or gotten into trouble again. But as Jeremy searched around the house, he noticed something that made his stomach drop.

There was blood coming from the door of his old utility trailer.

Jeremy walked closer, opened the trailer, and saw something no parent, neighbor, or human being should ever have to see. Inside, there was blood on the walls. There were handprints. And there was a young person’s body.

Panicked, Jeremy called 911.

“I just walked into my trailer to look for my son,” he told the dispatcher. “There’s a kid dead in my trailer.”

The dispatcher asked how old the person appeared to be.

Jeremy could barely get the words out. He said the victim looked young. Then he added the detail that made the call even more disturbing: the body was missing its arms and legs.

At that moment, Jeremy still did not know exactly who the victim was. His first fear was that it might be his own son. Rowdy was missing, and the scene was so shocking that Jeremy’s mind struggled to make sense of what he had found.

When officers from the Unified Police Department arrived, they moved quickly. They entered the home and began clearing rooms, calling out for anyone inside to make themselves known. They checked bedrooms, closets, and other areas of the property. There were unsecured guns and ammunition inside the house, but no sign of Rowdy.

The house was empty.

Outside, police activity began drawing attention from neighbors. One concerned neighbor approached and told officers that her grandson might be connected to the home.

His name was Nicholas “Nick” Vetishnik.

Nick was only fifteen years old. He was two years younger than Rowdy Aguilar, who was seventeen. Nick had already lived through more pain than most people face in a lifetime. When he was thirteen, he lost his mother to cancer. A little over a year later, his father died from a heart attack. After that, Nick went to live with his aunt and grandparents, the family members who loved him and tried to give him the stability he deserved.

Those who knew Nick described him as a gentle giant. He was tall, broad, and easy to notice, but his size was not what defined him. Behind that big frame was a soft-hearted teenager who cared deeply for his family.

One of the people closest to him was his elderly grandfather. As his grandfather became more fragile, Nick helped him, supported him, and made sure he did not fall. A video of Nick helping his grandfather even went viral on TikTok. In the video, Nick gently reassured him, saying, “I got you. I’m not going to let you fall. I promise.”

That small moment showed the kind of person Nick’s family already knew him to be. He was still a boy trying to find his place in the world, but he had a kind heart. He showed up for people. He protected the people he loved.

Now police were standing on a property where a young body had been found in a trailer, and the description matched Nick.

A detective interviewed Jeremy at the scene. Jeremy explained that the trailer belonged to him and that Rowdy and Nick sometimes went inside to smoke cigarettes or marijuana. Jeremy believed the victim might be Nick because of the curly hair and body size.

Jeremy also told detectives that a half-gallon bottle of tequila had gone missing from his bedroom. His bedroom door appeared to have been forced open. He believed Rowdy had broken in and taken the liquor.

Earlier that day, Jeremy had been working when Rowdy contacted him around 2:30 p.m. Rowdy asked when he would be home and whether he was working late. Jeremy said he was only getting lunch and would be back soon. When Jeremy asked what was wrong, Rowdy replied, “Nothing. I didn’t do anything wrong. Don’t worry.”

That message now looked deeply suspicious.

When Jeremy returned home, he found the broken bedroom door and the missing alcohol. He started looking for Rowdy, expecting to confront him. Then he went to the trailer and found the body.

Near the body, Jeremy also found Rowdy’s phone.

That was a major clue. There were bloody handprints, a dead body, Rowdy’s phone, and no Rowdy.

Police examined the victim and found details that matched Nick, including distinctive tattoos. The worst fear was confirmed: fifteen-year-old Nick Vetishnik had been murdered.

Rowdy Aguilar was now the main person police needed to find.

They did not have to search long.

By chance, officers spotted Rowdy in a nearby Target parking lot. When they approached him, they asked for identification. He said his name was Rowdy Aguilar. Officers told him to put down his backpack, turn around, and place his hands behind his head.

During the search, Rowdy told officers he had brass knuckles on him. He also had blood visible on his clothing, including his pants, socks, and shoes. He claimed one of his fingers was injured, but when officers asked what happened, he avoided giving a clear answer.

According to the officer who arrested him, Rowdy said he was on his way back to the crime scene. The officer later made sure that detail was documented in the report.

Rowdy was taken to the police station for questioning later that evening.

At first, he seemed restless and uncomfortable. He said he did not like being alone. When officers briefly left the room, he somehow managed to pull part of the restraint setup from the wall and step out of the interview room. He told them he was freaking out.

Once detectives sat down with him, Rowdy began talking about feeling different from other people. He said he had felt that way for a long time but did not know how to explain it. Whenever he tried to talk about it, he said people told him they did not understand him.

Before he could continue too far, detectives stopped him and read him his rights.

Then they asked him to walk them through his day.

Rowdy claimed he had been at the house of a girl named Dolores. He said he had been there since morning and left later in the evening. When detectives asked how he injured his hand, he said he had been helping cook food and cut himself while preparing ribs.

The detectives noticed the problem immediately. Rowdy had visible blood on his clothing. If he had been at someone else’s house cooking, why had he not cleaned himself up? Why was there blood on his socks and shoes?

They asked if he knew anyone named Nick or Nicholas.

Rowdy denied it.

He said he did not know anyone by that name. When detectives described Nick as a big guy, Rowdy still denied knowing him. He suggested he might have seen someone named Nick at school, but he insisted he did not really know him.

The detectives then confronted him with what they already knew.

They told Rowdy that Nick had been found in his father’s trailer. They also told him there was evidence proving he and Nick knew each other. The Aguilar family’s Ring doorbell camera had captured Nick and Rowdy entering the house together that morning.

Rowdy continued denying it.

He claimed he was not there. He said he had never met Nick. He said he did not know who detectives were talking about. He insisted that if they spoke to Dolores, she would confirm he had been at her house all day.

Detectives shifted tactics. Instead of arguing, they asked him to give them an hour-by-hour timeline.

Rowdy said he woke up at Dolores’s house around 9:00 a.m. He said they had breakfast at about 10:00. He claimed Dolores’s mother made eggs and bacon. Then, according to him, they watched the new Mortal Kombat movie. Around noon, he said Dolores made him a bologna and cheese sandwich. After that, he claimed they watched The Office on Netflix. Around 3:00 p.m., they supposedly decided to make ribs and wings. He said the wings had to thaw, and around 4:00 they started cutting and preparing the food.

Then he said he left around 5:00 p.m. and began walking back.

Detectives asked where Dolores lived. Rowdy said somewhere on 54th, but he did not know the exact street. Police had arrested him near Target on Redwood Road around 7:30 p.m.

The timeline did not work.

If Rowdy left around 5:00, it should not have taken him nearly three hours to walk that distance. There was a gap of multiple hours in his story.

The detectives pressed harder. They asked about Jeremy’s trailer. Rowdy claimed he did not even know the trailer belonged to his father. He said he thought it belonged to people across the street. He claimed he had never been inside.

That was another problem.

If Rowdy had never been inside the trailer, then nothing of his should have been found there. But his phone had been found at the scene. Jeremy had called Rowdy’s number, and the phone rang inside the trailer.

When detectives brought up the phone, Rowdy tried to distance himself from it. He said it was not his phone and that he had a new iPhone coming. Detectives noticed how quickly he seemed to have an explanation ready.

They also pointed to the blood on his socks.

Rowdy said it was dirt.

The detective told him it was blood.

Still, Rowdy denied everything. He said he had no reason to hurt anyone. He said he did not know Nick. He said he had never met him. He said he had not been there.

The detectives then moved to the subject of accountability. They asked Rowdy whether people should be held responsible when they do something wrong.

At first, he said no. Then he changed his answer and said, “Sometimes.”

The detective told him the situation looked worse the longer he denied knowing Nick. Denial, he explained, would make it look as though Rowdy had no remorse. If evidence proved he was there, and he still refused to admit even knowing the victim, that would not help him.

The detective told Rowdy this might be his only chance to explain what happened.

For a moment, Rowdy appeared to crack.

“I did it,” he said.

But almost immediately, he pulled back.

When detectives asked him to repeat it and explain why, he denied it again. He changed direction and said he had only met Nick once. He admitted he should have told them that, but he still tried to minimize their relationship.

The detectives already knew more. They knew Rowdy and Nick were connected on social media. They knew Nick had been at the house. They knew Rowdy’s father had said the two spent time together in the trailer. They knew the Ring camera had captured them entering the house together.

Eventually, Rowdy began offering a new version of events.

He said he was in the trailer with Nick. He claimed he felt like Nick was recording him. According to Rowdy, that made him angry, and he yelled. Then, he said, Nick suddenly became angry and grabbed a knife. Rowdy claimed Nick jabbed at him with it, and Rowdy caught the knife with his hand, which caused the injury.

Rowdy said he saw another knife and believed Nick was trying to kill him. He claimed he acted in self-defense. He said he swung a knife at Nick.

Detectives listened. But the story still did not explain what happened after Nick died.

If Rowdy had truly acted in self-defense, why did he not call 911? Why did he not run for help? Why did he not tell his father or the police immediately?

Instead, prosecutors later said Rowdy tried to hide evidence. Parts of Nick’s body had been removed and taken away from the trailer. That behavior suggested Rowdy knew what happened was not simple self-defense.

Detectives asked him about what happened after the stabbing. They wanted to know whether he had tried to get rid of evidence because he was afraid someone would find Nick.

At one point, Rowdy seemed to agree. But when detectives asked how he removed the body parts, he backed away again. He said he did not do it. Then he made a strange statement.

“I watched you do it,” he told one detective.

The detective asked what he meant.

Rowdy said it was like a video in his head. He said he saw someone who looked like the detective. He said that person was crying.

His story became more confusing and less believable.

While detectives questioned Rowdy, officers searching the Aguilar property made a major discovery. In a field behind the house, they found black and white garbage bags. Inside those bags were the missing parts of Nick’s body.

Detectives returned to the interview room and told Rowdy they had found them.

They gave him one last chance to explain what happened.

He said nothing.

The detectives left the room.

Only then did Rowdy begin begging to talk. He called out to them, apologized, and promised he would speak. But detectives told him the opportunity had passed. They said they were no longer going to ask him questions.

Officers then took photographs and DNA swabs. A doctor came in to draw blood and check Rowdy’s blood pressure. As he waited to be taken to jail, Rowdy made more strange comments about fear, death, darkness, and thoughts that seemed to appear out of nowhere.

He said he wanted help but felt he could not get it.

Despite his shifting explanations, police had enough evidence to charge him.

Investigators found a knife in the trailer that matched the other knives in the Aguilar home. It also matched Nick’s stab wounds. According to the evidence, Nick had been stabbed twenty-six times in the head and neck.

The Ring doorbell footage became critical to the timeline. It showed Nick and Rowdy going inside the house at 10:09 a.m. Later, at 1:20 p.m., Rowdy was seen going outside alone, wearing a bloody T-shirt. That T-shirt was later found in the trash. At around 1:30 p.m., Rowdy was seen carrying black and white garbage bags out to the field behind the house.

Those were the same kinds of bags officers later found containing the missing parts of Nick’s body.

Somewhere in that window of time, Nick was murdered.

In September 2025, Rowdy Aguilar pleaded guilty to aggravated murder with a mental health condition. The charge carried a minimum sentence of twenty-five years in prison.

For Nick’s family, that did not feel like enough.

Nick’s older sister spoke about the brutality of the crime and the pain of seeing Rowdy in court. She said he appeared smug and showed no real care for what he had done. To her, the crime felt deeply personal because of the way it was carried out.

Rowdy was sentenced to an indeterminate term of twenty-five years or more. Nick’s family hopes he will never be released on parole.

Even after the conviction, many questions remain unanswered.

Rowdy never gave a clear motive. People who knew both boys struggled to understand how something like this could happen. Some said Rowdy had changed as he got older. They said he started hanging out with the wrong people and his life began to fall apart.

One person who knew them said Rowdy had once seemed protective of Nick. After Nick’s mother died, Rowdy had reportedly been there for him. When Nick was bullied, Rowdy sometimes stepped in. That made the murder even more confusing.

Was it mental health? Was it drugs? Was it rage? Was Rowdy trying to create an explanation after the fact because the truth was too terrible to face?

By Rowdy’s own words, Nick had done nothing to him.

Nick was only fifteen. He was a teenager who had already lost both parents, a boy still searching for friendship and connection in a world that had taken too much from him far too soon. He trusted someone he considered a friend, and that trust was destroyed in the worst possible way.

When Nick was laid to rest, his family and friends gathered to say goodbye. In that moment, he was not a headline. He was not a case file. He was not just the victim in a horrifying crime.

He was a son. A grandson. A nephew. A brother. A friend.

He was deeply loved, and his absence would stay with his family for the rest of their lives.

At sentencing, Rowdy made a statement to Nick’s family.

He said, “I just want the family to know that Nick did absolutely nothing to me. I’m sorry for being a snake. I’m sorry for being a monster. But it won’t bring Nick back.”

And that is the part that stays with people.

An apology can be spoken in a courtroom. A sentence can be handed down. A case can be closed on paper.

But none of it gives Nick back his life.

None of it gives his family back the boy they loved.

And none of it fully explains how a teenager who had already survived so much heartbreak ended up losing his life at the hands of someone he trusted.
