The 17-year-old boy who drowned Monday afternoon after he jumped into the cold water of the Niagara River off Squaw Island to save a younger sister was identified by Buffalo Police on Tuesday as Mustafa Ismail of Buffalo.

A Buffalo Police underwater recovery team pulled him out of the water about 4 p.m. and he was declared dead at Erie County Medical Center. His seven-year-old sister, who he had jumped in to save, was pulled out of the water safely by another sister.
