Marty the Mouse became famous in 1974 after he made a home for himself in a box of marijuana stored in the evidence room of the San Jose, CA police station. Police were only able to lure him out by baiting a trap with marijuana seeds. (He ignored bacon, peanut butter, cheese, and a female mouse called Mata Hairy.) He became known as Marty the Marijuana Mouse.
But instead of killing him, he was first sent to UCLA to aid in studies of marijuana. Then he was returned to San Jose where he became a police mascot. When he died in Nov 1975, the nation mourned.
