STATEN ISLAND, N.Y. -- Police swarmed a home as they investigated a report of shots fired on a quiet street in Rossville, but by the time officers gained entry, the residence was empty.

However, police are trying to determine if there is a connection between the alleged shots fired and a man with a gunshot wound who walked into a hospital in Brooklyn, said a source with knowledge of the investigation.

Hostage negotiators and the Emergency Service Unit were called to a home in the 200 block of Gervil Street near Correll Avenue on Thursday night after a report of shots fired in the area.

Neighbors said they heard about three shots coming from the woods at the dead end of Gervil Street. The home where the individual allegedly was barricaded was near that dead end.

Then shortly before midnight on Thursday, a man walked into Woodhull Medical Center in Brooklyn seeking medical care. He claimed to be a Staten Islander who shot himself in the thigh, said the source with knowledge of the investigation.

The injured man then declined to provide further information, becoming uncooperative with police, the source told the Advance.
