Boy, 13, dies while jumping between Brooklyn rooftops

A game of roof hopping turned deadly in Brooklyn Friday, when two boys fell short of their destination and plummeted into an alleyway, police said.

A 13-year-old boy was killed and his 15-year-old friend was critically injured as they tried to leap the 7-foot gap between two buildings on Grove St. in Bushwick at 5:30 p.m., cops said.

Investigators say the pair plunged down 4 stories — or 40 feet. The 13-year-old — whose name was not released — was rushed him to Kings County Hospital but could not be saved.

His older pal survived the fall, and was at the same hospital in serious condition Friday night, with injuries to his pelvis, police said.

One witness said it appeared the 15-year-old boy landed on top of the younger one.

“It was boom, boom, the whole building shook,” said a cab driver named Luis who lives next door. “It looked like both fell face first,” he added.    NYDAILY NEWS
