E. Side thugs kill teen boxer

A 19-year-old aspiring boxer was stabbed to death by two thugs early yesterday after leaving a party on the Upper East Side, cops said.

Omar Gaspar had walked out of the gathering on East 75th Street and Second Avenue at 4 a.m. with his cousin and another pal when the killers, who also attended the party, approached them from behind.

“I have no idea what the problem was,” said the cousin, Richard Moreno, 23. “These guys had their arms behind their backs like they had a weapon.”

Suddenly, one of the attackers lunged at Gaspar’s pal with a knife, slicing him on the arm.

When Moreno turned to help, he saw Gaspar, who’s been training to be a boxer at a downtown gym, lying on the ground, struggling to breathe in a pool of blood.

“He just stabbed him real quick,” a heartbroken Moreno said. He lifted up his shirt and saw “a huge hole in his chest.”

Gaspar who died a short time later at New York Hospital, was “very outgoing, funny,” Moreno said.

“You look at him and the last thing you’d think of was trouble.”

The assailants fled towards First Avenue.
