SUICIDE BY COP - Man shot by San Francisco police left suicide notes: 'Don't blame yourself. I used you.'

A man who was shot and killed by San Francisco police officers left behind several suicide notes in his cellphone, including one addressed to police, authorities said Monday.

Officers shot Matthew Hoffman, 32, Sunday evening after he entered a restricted parking lot at a police station and brandished what appeared to be a handgun. It was actually an air gun, which fires small projectiles such as pellets or BBs.

San Francisco police made public a note titled "Dear Officer(s)" with the permission of Hoffman's father, authorities said in a statement.
