The fatal stabbing of a Queens parks department worker stemmed from a fight with a colleague over using a black plastic garbage bag, police sources revealed today.
Ezra Black, 31, had argued for hours with Robert Swann, 51, on Tuesday after Swann told him to use the black garbage bag at a Queens recreation center, sources said.
“Listen, I don’t want to go back to jail, but I’m gonna kill you,” Swann said before he went to get a wooden-handled knife from the center’s cafeteria, sources said.
He then allegedly attacked Black outside the building.
“Rob just stabbed me!” Black shouted in one of his last breaths, sources said.
After the slaying Swann walked to Flushing Meadow Park, where Parks Enforcement Patrol officers cornered him near the Unisphere and NYPD cops arrived to arrest him.
Swann, who had worked at the center for five months, told authorities Black bullied him and called him names but supervisors did nothing when he complained, sources added.
The two men were in a Job Training Participants program for welfare recipients.
Swann is being held without bail on murder, tampering with physical evidence and weapons possession charges.
