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.
Barnette didn't have a designated route but some residents say they've seen him deliver their mail before.
James Cox, said, "It's a tragedy. I've seen him before. I didn't really know him. I asked him one time if the road was closed other than, it's unfortunate."
Kelly Crisp, a resident says, "It's sad, surprised it happened here. It's sad he was so young. And it's a little scary they don't know what's going."
"It's just very important that you think about it during the holiday season. It would be imperative to give the Barnette family some closure here. This was a horrible crime that occurred here," said Officer 1st Class Nicole Hubbard with the Prince George's Co. Police.
US inspectors say solving this murder is their top priority. Along with Crime Solvers they're offering a combined $125,000 reward.
They say there have been two additional postal workers killed on the job in the last four years including one in Miami due to a robbery and earlier this year a letter carrier was shot and killed in Texas in a dispute over mail service. Both of those cases have been solved.
In Barnette's case, investigators say they don't know why anyone would want to shoot him but are looking into robbery as a possible motive.
Schissler says, "We're exploring that possibility but we are exploring all possible leads and all possibilities for the murder."
Killing a US postal worker in the line of work is a federal crime and the person or persons responsible, when caught, could face the death penalty.
