Assailant Killer Gives Up

An elderly plumber who shot and killed a knife-wielding teen-ager, one of two assailants, during an apparent robbery attempt in Chicago surrendered to police and was released as soon as authorities decided not to file charges against him. “I’m sorry for what happened,” Harold Brown, 68, said as he left police headquarters. “I still feel afraid.” The shooting occurred Thursday night as Brown was carrying two bags of groceries home, and police implored him to turn himself in for questioning. Brown at first held off, saying through an intermediary that he feared retaliation and extensive publicity.
