A woman turned her huge boobs into deadly weapons to kill her lover in a drunken row.
The victim, who has not been named, was heard shouting for Donna Lange to stop squashing him during a noisy row in the trailer they shared in Washington state.
His 51-year-old partner, who weighs 14st (89kg), may face involulntary manslaughter charges, police said.
Police who entered their mobile home in the town of Everett claimed they found her sitting on the deceased man. He weighed a stone less than her.
Lange was allegedly very drunk at the time of the incident and told officers she had no idea what had happened to her boyfriend.
Attempts to find out details from three possible witnesses were foiled because they were all so drunk.
The case resembles a recent incident in Germany in which a man fled naked into the street after claiming his wife had tried to asphyxiate him with her bosom.
