A ski mask wasn’t enough of a disguise for the gunman who robbed the Shell station Sunday morning as his voice has landed him behind bars for the pre-dawn heist.The suspect, Bryan Bridgeman, 33, is being held at Warren County Jail under $100,000 bond facing charges of aggravated robbery. The crime carries eight to 12 years in prison.Bridgeman is charged for walking into the Shell Station around 3:30 a.m. Sunday morning and robbing the lone female clerk at gunpoint. The clerk was uninjured but the gunman was able to get away with money and checks from the cash drawer.While shielding his face from the surveillance cameras by wearing a mask, it was his voice that gave him away, according to McMinnville Police Detective Nicole Mosley.“I was talking to Sgt. Ben Cantrell about the case and when he heard about the voice he recognized the description,” Mosley revealed, noting Bridgeman speaks with a peculiar accent and has a nervous cough when he talks.
