Erie County Sheriff's deputies say they've arrested a man who threatened to open fire at the factory where he works and who had a loaded gun and bulletproof vest in his car. Workers at the Ventra auto parts factory just outside Sandusky told officers the man showed up angry at work Tuesday. One of his co-workers says 23-year-old Austin Hines said he was so upset he wanted to shoot the place up. Hines was being held in jail on charges of carrying a concealed weapon, aggravated menacing and improperly handling a firearm. He is scheduled for an arraignment hearing Wednesday morning at Erie County Municipal Court.
