A prisoner who was hurt while trying to escape from Colorado's Pueblo County Jail has sued the sheriff for making it too easy for him, reports the Los Angeles Times. The prisoner was seriously injured when he fell 40 feet while trying to get down from the prison's roof using a ladder of bedsheets and mattress covers. The prisoner had removed ceiling tiles in the shower to ascend the roof. The Los Angeles Times says that the amount of money sought is unspecified.
