The U.S. Marshals Service has arrested a man suspected of killing two brothers inside their family's convenience store.
 The Bradenton Herald reports that 25-year-old Devin Chandler was arrested in Tampa Tuesday. He faces two counts of murder and one count of armed robbery.
Investigators say 23-year-old Khasem Yousef and 17-year-old Faares Yousef were killed Monday afternoon at their family's Manatee County store.
Video surveillance shows Chandler walking into the store, picking up a few items and then walking up to the counter. Police say that instead of paying, Chandler shot both brothers in the head.
Chandler was released from prison in September 2011 after serving less than two years on a three-year sentence for a conviction of attempted armed robbery with a weapon. Records show he's on probation
