Man dies after showing up at Brooklyn hospital with gunshot wound

A 45-year-old man died after showing up at a Brooklyn hospital with a gunshot wound to the torso — and cops are still trying to determine when and at what location he was shot.

Police were called to Brookdale University Hospital at 2:37 p.m. Wednesday after Gamaliel Oliver arrived by private means mortally wounded.

Oliver died a short time later from a gunshot wound to his abdomen. He lived in East New York, according to cops.

Cops are unsure when and where the shooting took place as they continue to investigate the homicide.
