Two men and a woman were killed in an apartment on Manhattan's Upper West side, police said Saturday. The bodies were found, with a gun nearby, in an upscale building Saturday evening, police Sgt. Kevin Hayes said. It was unclear when they died. Investigators did not know whether the three were related or if any of them lived in the eighth-floor apartment, Hayes said. Their names and ages were not released. No one else was there when the woman and one man were found on the floor, and a second man was found in a chair, the sergeant said. Detectives were talking to residents of the 10-story structure with decorative wrought-iron doors on a quiet residential block. A man answering the phone at the building office declined to comment and hung up.
