Denver- A former gay porn actor is scheduled to appear in a Denver courtroom Wednesday on allegations that he gunned down a prominent businessman less than three weeks ago.

Timothy Boham, 25, was arrested Nov. 16 at a U.S.-Mexico border checkpoint in Lukeville, Ariz., three days after police discovered that his boss, John Kelso, had been shot to death in his upscale suburban Denver home.

Boham, who appeared in films such as “Little Big League” and “Ripe” under the stage name Marcus Allen, waived extradition last week and returned to Colorado over the weekend, according to Denver District Attorney spokeswoman Lynn Kimbrough.

Boham is set to appear in court Wednesday to be formally advised of felony murder and aggravated robbery charges against him.

He was being held without bond, Kimbrough told CourtTVnews.com.

Police believe Boham broke into Kelso’s home and shot the 43-year-old to death sometime between Nov. 11 and Nov. 13, when a housekeeper discovered the body.

Authorities have not revealed evidence linking Boham to the murder.

Kelso, who was president of Professional Recovery Systems, had recently hired Boham to work as a debt collector, following Boham’s departure from the gay porn industry almost a year ago.

Boham fled Colorado shortly after Kelso’s body was discovered.

“John was a very kind-hearted person who went out of his way to help others,” said Chris Bridges, a vice president at Kelso’s company. “When he was in the office, he was strictly business, but he had a human touch that he extended to everyone he worked with.”

Roger Maier with the U.S. Customs and Border Protection said Boham was arrested on U.S. soil after officers found him loitering outside an inspection facility on the U.S.-Mexico border.

“The officers arrested him after he identified himself as the subject of a murder warrant out of Colorado,” Maier told CourtTVnews.com.
