Anthony Little AKA No-Heart Anthony is a brother to Stick Up Artist Omar Little, he is first mentioned on the episode "The Pager" by Bubbles when he mentions him to Kima Greggs, Kima somehow hasnt heard of him, then Detective Jimmy McNulty knows about him, apparently hes locked up for robbing a jewelry store

Anthony's nickname comes from a suicide attempt following a botched, armed robbery. Upon being surrounded, and his realisation there was no escape, he turned his gun on himself, loosing a single bullet into his chest. The suicide attempt failed, and Anthony woke up in the hospital with a contact wound and a new nickname.
