DOYLESTOWN, Pa. (AP) — A Philadelphia-area man who survived a suicide pact that left his mother dead will not face a homicide trial.

A Bucks County judge has dropped a homicide charge against 30-year-old Koustantinos “Gus” Yiambilis in the April death of his 59-year-old mother, Karen.

Judge Albert Cepparulo in a ruling Tuesday says he found no evidence of malice on the son’s part.

Yiambilis is still charged with two felonies, aiding in suicide and risking a catastrophe. He remains in custody on $500,000 bail.

Authorities responding to fumes at their Bensalem apartment found the mother dead and the son disoriented from carbon monoxide poisoning. Investigators say the room was taped shut while a gas generator ran.

Defense lawyer William Goldman Jr. says justice was served because his client did not kill his mother.
