Police: Postal Worker Killed on Duty in Maryland Police say a postal worker has been shot to death while delivering mail about 10 miles from the nation's capital. Police said they were called to a street Saturday evening in Landover and found 26-year-old Tyson Jerome Barnette dead from apparent gunshot wounds. Police are trying to identify suspects and a motive. U.S. Postal Service spokesman Frank Schissler says it's rare for a postal worker to be killed while delivering mail, but it has happened. A postal worker was killed north of Houston in May and in 2010, a deliveryman in Miami was shot to death. The U.S. Postal Inspection Service is offering a $100,000 reward for information that leads to an arrest in the shooting.
