AURORA, Colo. — A man who fatally shot the new boyfriend of his former girlfriend was found guilty of first-degree murder this week, according to the 18th Judicial District Attorney's Office.
An Arapahoe County jury on Wednesday deliberated about three hours before returning the verdict against Joseph McCaughin, 20, of Aurora.
He was charged in connection with the killing of Ryan Robertson.

“It’s tragic to see yet another young man’s life cut short by the petty jealousy of a man with a gun,” said District Attorney John Kellner. “Not only did this defendant kill another person, but he put little kids in harm’s way as he was shooting. Clearly, he is a danger to this community.”
On May 6, 2019, McCaughin killed Robertson, who was 16 years old when he died. Earlier that day, McCaughin had broken into the home of his former girlfriend, who had begun dating Robertson. He told her, “If I ever see (Robertson) again, I will kill you and him.”
That evening, McCaughin and Robertson encountered each other near Wagon Trail Park in Aurora. Robertson had two friends with him. McCaughin and Robertson exchanged words, and then McCaughin shot six to seven times at Robertson before running away.
Robertson was shot twice and died from his injuries. When McCaughin started firing, surveillance video and witnesses confirmed he was firing towards Independence Elementary School, where numerous adults and children were outside and in the line of fire, though fortunately no one else was injured.
Aurora Police found McCaughin in Georgia eight days later.
“McCaughin made his intent and his plan crystal clear,” Deputy District Attorney Grant Grosgebauer told the jury. “He went looking for his victim and he was carrying a gun.”
Grosgebauer tried the case with Chief Deputy District Attorney Gary Dawson.
“This defendant told police — and his mother — that he wasn’t the shooter, and that he was at the Southlands mall at the time of the shooting. Witnesses and his cellphone placed him at the scene. At trial, out of desperation he claimed that this murder was in self-defense, but the evidence proved otherwise,” Dawson said.
Sentencing is set for Nov. 9. The statutory penalty for first-degree murder is life in prison without the possibility of parole.
