A warehouse worker said in a frantic 911 call that he was shot in the neck and then took the gun from a co-worker after he had shot several others. Two people died and four were injured in the Ohio shooting that sent panicked employees fleeing.

A man was arrested at a house in Columbus on Wednesday morning, after he had fled the scene of the shooting on Tuesday night.
