A 19-year-old Aurora man allegedly stabbed his stepfather repeatedly and then recorded the last moments of the man’s life in a Snapchat video taken as he bled to death, court records indicate.

“Hey guys I just killed him. I just killed him. I just killed him,” Nickolas Khalil Vinson could be heard saying in the video. A man was face down, covered in blood. A woman kneeling next to the man was screaming, “Lemar, can you hear me? Can you hear me? No!” The video than panned back to the person making it, identified as Nick Vinson.

Nick Vinson had shared the video with friends on the social media platform. Aurora police later charged him with first-degree murder in the Friday night stabbing of his 50-year-old stepfather, Oscar Lemar Owensby, at a home in the 2700 block of South Rifle Street.

Owensby was the common-law spouse of Celena Vinson, the woman seen kneeling in the Snapchat video. She is the biological mother of Nick and his 15-year-old brother, Kyle. The Vinsons had lived with Owensby for 14 years.

Nick Vinson called his brother just before 7 p.m. Friday and told him that he had just stabbed their stepdad because Owensby “wanted to throw him out of the house,” according to an arrest warrant affidavit.

Celena Vinson, who witnessed the stabbing, called police, the affidavit says.

A policeman called Nick Vinson, who allegedly admitted killing his stepfather and said he had driven away from their home in his mother’s Ford Explorer. He told police he was looking for his friends so he could say goodbye and tell them he would be away for a long time, the affidavit says.

He told the officer he would drive home, but police stopped him before he got to the house. The teen was covered with blood and had a large cut on top of his left hand. When Vinson opened the driver’s side door, blood dripped on the ground, investigators said.

A crime scene investigation indicated Owensby had been stabbed near Vinson’s bedroom in the basement of the tri-level home. A trail of bloody footprints led up to the main floor and out to the garage.

Vinson allegedly used a 7-inch blade with a brass-knuckle-style handle to stab Owensby between seven and nine times in the neck, back, side and left shoulder, the affidavit says. His aorta was perforated by a stab wound to his back and police said they found arterial blood splattering the walls of the basement.

Owensby was taken to a hospital where he was pronounced dead.

Investigators found Vinson’s Snapchat video after the mom of a girl who saw it called police.

Vinson told police he had been arguing with his stepfather in a series of text messages. Owensby wanted him to do chores around the house and chip in money for the household, the affidavit says.

While texting, the two agreed to a fist fight.

An argument started when Owensby returned to the house. He then left the home again to pick up his wife. When they got back to the house, Celena Vinson went downstairs and told her son the three of them needed to talk. Nick Vinson refused to go upstairs.

Vinson told police Owensby stood at the top of the stairs and challenged him to come upstairs and fight. Owensby then went down into the basement and was about to hit Vinson with his fist, when the teen stabbed him near the neck, the affidavit says.

Vinson said he kept stabbing Owensby “to end it” because he didn’t want him to suffer, the affidavit says.
