(Winchester, IN)--The search continued Tuesday morning for an escaped Randolph County inmate. 26-year-old Robert Lewis has been gone since 3:30 Monday morning. Monday night, Randolph County Chief Deputy Douglas Fritz said that Lewis is now believed to be driving a black 1990 Ford F-150 pickup truck with a gray stripe near the running board. He was seen in Richmond early Monday morning, but there have been no further sightings. Lewis was due to be sentenced for burglary late next week. On Monday, he was charged with escape. That could add another six years to his sentence.
