(Shutter Stock) (Newser) – A man and his son and grandson were found shot to death in an apartment in an upscale Manhattan neighborhood today, with a fourth man found dead in the back yard and a wounded woman taken to a hospital, police said. The three family members were found inside the third-floor apartment. They were investigating whether the fourth man, found dead from a fall, was the gunman. Detectives suspect that the shootings were drug-related and that the gunman died trying to flee the scene, said a police spokesman. Police recovered a semiautomatic handgun in the third-floor apartment in the rear of the walk-up building. No arrests had been made. The killings were reported at 1:45pm at the building on Amsterdam Avenue near West 84th Street, a busy commercial strip in a tree-lined residential neighborhood a few blocks from Central Park.
