Investigators are still trying to find the family of the man who was crushed to death in an elevator shaft at Montgomery station last weekend, the San Francisco Medical Examiner said Thursday.

The elevator was reported stuck at about 9:35 p.m., authorities said, and a person who was inside it at the time said he heard a crunching sound and scream while riding from the Muni level up to the concourse level.

Fire personnel then found a man dead on top of the elevator. Foul play is not suspected and investigators are now determining how the man got inside the shaft.

The man appeared to be homeless, officials said, as he was surrounded by bedding and other personal belongings and lacked identification.

Anyone with information about the man’s identity is encouraged to call the San Francisco Medical Examiner’s Office at (415) 553-1694
