A former Sardis police officer known by his co-workers as “Robocop” is back in jail after a trail of trouble since his resignation in 2009. Winard Dewayne Burke, 33, of Mock Street in Sylvania, turned himself in Thursday morning after breaking into a Sylvania police lieutenant’s patrol car while it was parked in front of the department Sunday, police said. According to Sylvania police reports, Burke approached the police department while officers were responding to a call.
