Two arrested after several body parts — including 2 heads — discovered outside LI school, popular park

Two people have been arrested in connection with the discovery of several body parts — including two severed heads — in a popular Long Island Park last week, The Post has learned.

The pair of arrests came as cops raided a home on Railroad Avenue in Amityville, New York, early Tuesday, police sources told The Post.

The first body part was found Thursday morning by a girl walking to school with a group of friends on Siegal Boulevard — which is on the east side of Southards Park in Babylon, Suffolk County.

When authorities swept the area, they found parts of several other limbs that cops say belong to a man and a woman.

Investigators have said they’re hoping DNA tests — as well as the man’s tattooed left arm — will help them identify the victims.
