An accused killer told cops a male friend made an unwanted sexual advance toward him, sending him into a homicidal rage, sources said.

Ronald Jones, 55, was arraigned on second-degree murder charges Monday after the medical examiner's office ruled that Staten Island resident Robert Jenkins was choked to death.

Some of the victim's enraged relatives were so overcome by emotion after spotting the suspect in court, they had to be held back. "That was my father!" Thomas Jenkins, 38, said angrily. The suspect didn't respond. And he didn't make eye contact with the victim's 30 or so relatives gathered in court. When the judge denied Jones bail, mourners broke out in applause. Robert Jenkins, 68, a retired mechanic and grandfather of 11, was found dead early Saturday in his West Brighton home. He had been drinking cognac with Jones for hours. Jones was visiting from Maryland.
