A former gay porn actor allegedly told his sister that he killed a prominent Denver businessman during a botched attempt to steal money from his personal safe, according to police records.

Timothy Boham, 25, appeared in court Wednesday on charges of first-degree murder, felony murder and aggravated robbery for the November shooting death of John "J.P." Kelso.

A housekeeper Kelso’s body in a bathtub in his upscale suburban Denver home on Nov. 13, dead from a single gunshot wound to the head.

A safe was also missing from the closet of the master bedroom.

Kelso, who was openly gay, according to news reports, was the president and founder of Professional Recovery Systems, a debt collection company.

The day after his body was discovered, Boham’s sister, Katherine, allegedly contacted Denver police to report that Boham had confessed to the killing.

Boham was "upset" when he visited his sister after the shooting, according to the police affidavit. He allegedly told her that Kelso had a safe in his home containing between $100,000 and $400,000.

"Kelso would not open the safe, and he and Timothy struggled for a bit," Denver Police Lt. J.W. Priest wrote in the arrest warrant application. "During this altercation, Timothy shot Kelso."

Katherine Boham also told police that her brother said he tried to clean up the scene before fleeing with the safe.

Boham was arrested on Nov. 16 at the U.S.-Mexico border in Lukeville, Ariz., after identifying himself as the subject of a murder warrant to Customs and Border officers. He was brought back to Colorado over the weekend and is being held without bond.

Boham has appeared in gay porn films such as "Through the Woods" and "Ace in the Hole" under the stage name Marcus Allen. Kelso had recently hired Boham following his departure from the adult film business.

Boham had previously been arrested for alleged assault and making threats, but the charges were dismissed.

Kelso also has an extensive record for driving under the influence, driving without a license and driving with a prior DUI arrest. Despite his seeming affluence, state and federal records indicate that he declared bankruptcy multiple times over the years, with arrests for forgery and fraud dating back to 1988.

Boham’s preliminary hearing was set for Jan. 17.
