Montana police say a man who may have been using a large garbage bin as shelter from the cold was apparently crushed when the bin was emptied.

The man's body was found in a city waste truck at 6:30 a.m. Saturday.

Billings police Sgt. Jay Berry says the victim was found "partially in a sleeping bag" and may have been using the garbage bin as shelter.

Yellowstone County Deputy Coroner Chad Fehr says the man died of blunt force injuries to the chest and that his death has been ruled accidental.

Berry says the man's injuries are consistent with the operation of a garbage truck.
