A private prison transportation company has apparently lost an inmate being taken to Philadelphia.
Authorities say 33-year-old Sylvester Mitchell was being moved from Florida to face attempted murder charges in Pennsylvania. He was gone when the van arrived in Philadelphia early Thursday.
Police aren't sure how or where Mitchell got away. They say he was held in shackles.
There was a similar case in September when a shackled man escaped from a guard at the Philadelphia airport. He was captured a week later.
The company in both cases was Tennessee-based Prisoner Transportation Services of America. A company spokesman declined to comment on the latest escape.
