A 19-year-old aspiring boxer was stabbed to death by two assailants after leaving a party on the Upper East Side, police said.
A day after the senseless crime, police arrested Exequiel Reyes, 23, of the Bronx. He was charged with murder and related offenses.
The victim, 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 approached them from behind, cops said.
The two alleged killers had also been at the party, the New York Post reported, and a dispute had started during the gathering.
"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," the report said.
"He just stabbed him real quick," a heartbroken Moreno said. He lifted up his shirt and saw "a huge hole in his chest."
Gaspar died a short time later at New York Hospital.
The assailants fled towards First Avenue.
