A court has heard details of an "out of control" sex life at the murder trial of interior designer David McNee. McNee used to cruise red light districts looking for rent boys, was promiscuous, and indulged in group sex, according to David Matulovich, a friend of McNee's. "Guys he would sleep with for a week or so would then say they were going back to their wives and then one month, two months later ... would show up at David's again," said Matulovich in a written statement. "There could have been maybe 20 or 30 men ... these people, David would tell me were getting jealous... David was apprehensive about the situation. He was concerned about the lack of control." 23-year-old Phillip Layton Edwards is accused of murdering McNee after he was picked up on K' Rd and taken back to the designer's home. Edwards admits to punching McNee in the head up to 40 times because he started to come onto him and tried to touch him. Police at the murder scene found blood on the bed, floor, furniture, walls and even the ceiling.
