LANDOVER, Md. (WUSA9) -- On Saturday, Prince George's County Police investigators and U.S. Inspectors were out canvassing the same route where Tyson Barnette was murdered.
They are looking for any new leads that will lead them to Barnette's killer. The letter carrier was shot to death while on his assigned route in Landover, Md.
US Postal Inspectors and Prince George's County detectives went door to door revisiting 26-year-old Tyson Barnette's assigned route, the day he was killed.
Frank Schissler, a Postal inspector says, "Hopefully there's someone who knows something. It might not be something that happened right before he was killed or after he was killed. It may have occurred another day. There may have been some incident that could have led to this."
One week ago Saturday, Barnette was near the end of his route in the 1600 block of Reed Street and Jutewood Avenue in Landover around 7:20 in the evening, when he was gunned down.
