NEW YORK (TIP): Four people were shot – one fatally -while two others were stabbed in separate incidents in the Bronx, Queens and Manhattan late Thursday and early Friday, police said.

First, in the Bronx, two groups of men were in an argument near 183rd St. and Jerome Ave. in University Heights around 10:55 p.m., cops said, when shots were fired and people fled.

Cops found 16-year-old Justin Morris shot multiple times to the back nearby on Jerome Ave. near Buchanan Place. He died at the scene.

A 19-year-old man, whose name was not released, was later found by cops on 183rd St. and Jerome Ave. with three gunshot wounds, two to his back and one in the buttocks. He was taken to St. Barnabas Hospital, where he’s in stable condition.

“There were two guys lying on the ground,” said a man, who didn’t want to be named and just got out the 183rd St. train station.

“One guy looked dead.”
