On Tuesday, the mother of a 13-year-old boy shot Friday night in ­Roxbury while he was walking to choir practice implored anyone respon­sible for the ­brazen attack to surrender.

“Turn yourself in,” said ­Shirley Clarke, the mother of Gabriel Clarke, who is recovering from his injuries at Boston Medical Center. “You have hurt an innocent child, and to avoid hurting others, stop and turn yourself in.”
