Arapahoe County District Court Judge Elizabeth Weishaupl on Thursday imposed the statutory sentence on Cameron Scott Costello, 26, for the murder of Brandon Brabson, who was 33 years old.

Brabson was shot and killed June 23, 2020, at the Sable Cove Apartment complex in Aurora. On July 28, a jury found Costello guilty of first-degree murder in Brabson’s death.

“This man with a gun took matters into his own hands and executed a father of three,” said District Attorney John Kellner. “This sentence is appropriate for a murder in cold blood.

“No sentence will bring Mr. Brabson back to his family, but perhaps they can find some healing in putting this phase behind them.”

Brabson was at the apartment complex that night trying to speak with his former girlfriend, who had a restraining order against him.

The former girlfriend was disturbed that Brabson was trying to contact her and asked for assistance from friends and neighbors in urging him to leave.

Costello was at the apartment complex to deliver something to his ex-wife, who lived there. He was seen on surveillance video with Brabson moments before he was shot.

When Brabson’s ex-girlfriend heard the gunshot, she and some people who were with her rushed to see what had happened and found Brabson’s body alone and bleeding. They believed he had killed himself, but no gun was found; Brabson had no weapon.

After Aurora police identified Costello, he was arrested. He had with him the gun that had killed Brabson.

Brabson’s mother and sister spoke to the court during sentencing on Sept. 9.

Brabson’s sister spoke of the loss felt by his three daughters, and of the hole in their lives without a father.

“My brother, Brandon, was not a threat to (the defendant). Brandon certainly didn’t deserve that bullet that (the defendant) shot from behind him, straight into his brain stem … my brother, Brandon, went down like a soldier when (the defendant) shot him in such a cowardly way.”

Brabson’s mother told the judge Costello “ripped my heart out forever.” She spoke of unanswered questions and how her son’s murder “haunts me every hour of every day and every hour of every night since Brandon’s execution.”

Senior Deputy District Attorney Jake Adkins prosecuted the case with Deputy District Attorney Justin Friedberg. Adkins acknowledged there seemed to be very little motive for the murder.

“We have never been able to answer why.” Adkins said during his brief sentencing argument. “Mr. Brabson was executed in the street for very little benefit. … It was a callous and senseless act that shows utter disregard for the value of human life.”
