UPDATE | Sheriff says Ohio teen had gun all morning day of shooting

HAMILTON, Ohio (AP) — An Ohio sheriff says the 14-year-old suspect in a school shooting apparently was carrying a handgun all morning before he jumped up in the cafeteria and opened fire.

Sheriff Richard Jones says it's believed the youth obtained a .380-caliber gun from a family member, but the investigation is continuing. He also repeated that authorities also believe they know a motive in the Monday lunchtime shooting, but aren't releasing any details to avoid jeopardizing the case.

Jones says as terrifying as the shooting was, it's a relief that no lives were lost. He says it's the first school shooting in memory in Butler County in southwest Ohio, although there have been repeated school lock downs because of threats in recent months.

He calls on school officials throughout Ohio's 88 counties to recognize that such shootings can happen anywhere, and to take action to be sure their schools are protected.

The youth's attorney denied the charges today in juvenile court.
