A human head was found in a Long Island neighborhood where severed arms turned up in two separate residential yards last week, authorities say.

Hempstead police say the head was found at about 5 p.m. Thursday on Boylston Street in Hempstead, close to where the two arms were found a day apart.

A Hempstead homeowner found a human arm with women's clothing attached to it in his front yard on Webb Avenue on July 9. The next day, someone else discovered another human arm in their yard about a half-mile away, near Stewart Avenue and Cornell Street.

Police were looking into whether the arms are related to to the discovery of a partially dismembered body in a municipal parking lot in Bay Shore on July 8.

The remains discovered in the lot July 8 were found by two people walking to the ferry on Fire Island.

Homicide detectives in Nassau and Suffolk counties are investigating as they await DNA results on the other body parts.
