The sister of the 17-year-old boy suspected in an Ohio school shooting that injured two says she doesn't know his motives.

She tells WHIO-TV that her brother made a mistake but, in her words, "he's not a monster." 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. The prosecutor says he'll seek to have the case moved from juvenile court to adult court.

The school was resuming classes Tuesday.
