WEST LIBERTY — The sister of the 17-year-old boy suspected in an Ohio school shooting that injured two says he made a mistake, but he’s “not a monster.” She tells WHIO-TV that she doesn’t know her brother’s motives. She says she hasn’t had contact with him since Friday, when authorities allege he fired a 12-gauge shotgun at a high school in West Liberty, 45 miles northwest of Columbus. The teen’s attorney, Michael Pentecost, told the Springfield News-Sun he can’t discuss his client’s mental condition or possible motives. The Associated Press generally doesn’t identify juveniles charged with crimes. The teen remains in custody.
