Staten Island slay mystery; mortally wounded gun victim dumped at hospital, cops seek facts of killing

A mortally wounded gunshot victim was dumped at a Staten Island hospital — and detectives tried Thursday to determine where he was shot, police said.

A man and woman dropped off the unconscious and unresponsive victim at Staten Island University Hospital South in Princes Bay at about 8:10 p.m. Wednesday, cops said.

The man, 36, was initially believed to have just a puncture wound to what police called his “upper right arm area.”

But doctors soon determined the man had a bullet lodged in his chest — and by then, the people who dropped him off had fled the hospital.

The man died at the hospital.

The victim’s name was not immediately released as cops investigated the circumstances of the shooting.
