DENVER -- The man suspected of killing a Denver businessman was a gay-porn actor, the Rocky Mountain News reported in its Friday editions.

Timothy Boham, 25, was arrested Thursday on the U.S-Mexico border after he was seen loitering near the border crossing station in Lukeville, Ariz.

Boham was named in a first-degree murder warrant issued Wednesday in connection with the death of John Paul Kelso, 43, of Denver.

A cleaning person found Kelso's body in his Congress Park home on Monday. He had been shot and his body was in a bathtub. Police believe he was killed over the weekend.

Boham starred in gay porn movies under the stage name "Marcus Allen," according to a the News. The editor of a publication that covers the gay porn industry told the newspaper that Boham was a "fair big star."

Police are investigating the relationship between Boham and Kelso.
