A man on trial for killing another man on First Street in Bangor last year initially told police he didn’t know why the victim was bleeding. But a witness sayS 42-year-old Jason Trickett quickly admitted, he’d stabbed the man. Trickett’s charged with manslaughter in the death of 38-year-old Andy Smith. Smith died after a fight that spilled into the street last May. Tuesday, prosecutors played back the recording of Trickett’s first interview with police. When they asked him how Smith ended up bleeding, Trickett said he didn’t know and that someone said Smith had cut himself. But a man who was in the apartment where the trouble started brewing said Trickett ran back inside after the fight and said, “I stabbed someone”, then threw what appeared to be Smith’s knife into the garbage in the kitchen. Lawyers for Trickett don’t deny he stabbed Smith but say he did so in self defense. Several witnesses say Smith was drunk and swinging a board after he’d beaten up two women he knew. A medical examiner’s report says Smith’s blood alcohol level was twice the legal limit. Trickett waived his right to a jury trial and the case is being presented to a judge.
