A seasonal employee with the city Parks Department fatally knifed a co-worker yesterday at a Queens recreation center, law enforcement sources told The Post.
The bloodshed occurred at about 3:15 p.m. — some five hours after Mayor Bloomberg was at the Al Oerter Recreation Center on Fowler Avenue in Flushing for a press conference.
Ezra Black, 31, and Robert Swann, 51, first started fighting near a shed at the center.
The younger man ran off, but was chased, allegedly by Swann, into a kitchen area where he was mortally wounded, the sources said.
Another employee at the recreation center said Black had just started working there in the past few days.
“He hadn’t even picked up his first Check yet,” the worker said.
Swann was nabbed nearby at the Unisphere in Flushing Meadows Park by cops assigned to the US Open, sources said.
He was charged with murder and weapons possession.
