Police in Long Island are investigating two deaths that appear to be connected: investigators suspect that the beheading of a woman in Farmingdale is linked to a man's fatal jump in front of a Long Island Rail Road train.

According to Newsday, "Shortly before 8 p.m. Tuesday police received a call to 130 Secatogue Ave., where they found the body of a homicide victim, a woman in her 60s, outside the apartment building at that address, said Det. Michael Bitsko, a police spokesman. A second victim, a male in his 30s, was struck and killed by a Long Island Rail Road train about 1,000 feet away from the homicide scene. He was hit at about 8:20 p.m., police said."

Initially, police thought the beheading was a Halloween prank.

A witness who saw the female victim told the Daily News, "The body’s feet were at the curb, the shoulders were at the middle of the street. The head was across the street... I’ve seen some gruesome stuff in my years of living ... but nothing like this. I didn’t expect to see something like this, especially not out here." A police source tells the Daily News "the woman’s head may have been kicked across the street after the murder."

LIRR passengers were held on the train for hours while police investigated.

The police say there is a link between the woman and man; it's believed they may have been mother-and-son.
