BABYLON, N.Y. (PIX11) – Two sets of human remains were found in a Long Island park on Thursday, authorities announced on Friday.

Police discovered a head, leg, and arm — all belonging to an unidentified woman — scattered on the east and west ends of Southards Pond Park in Babylon. The arms of a man were also found at the park, officials said. One of the arms has a distinct tattoo and the fingertips are missing.

Investigators are waiting on an autopsy report to reveal more information on the cause of death for both victims.

A high school student on her way to school made the gruesome discovery of one of the male arms along Siegel Boulevard, which runs alongside Southards Pond Park, around 8:40 a.m. Thursday, sparking the police investigation.

A police cadaver dog searching the western side of the park found a leg sticking out of a pile of leaves on Graham Place between Beverly Road and Martin Place, authorities said. Investigators told PIX11 News the same dog also found a right arm on the eastern side of the park, about 20 feet from where the left arm was discovered.

The body parts appear to have been dumped recently, according to authorities.
