Police have taken a man into custody on charges related to the highway homicide of a United States Postal Service truck driver in downtown Dallas earlier this week.

Twenty-Five Year Old Could Face Federal Charges For Slaying Of USPS Driver

USPS truck driver fatally shot on Dallas highway

The suspect has been identified as 25 year old Donnie Ferrell. According to Fox 4 News, Ferrell was arrested in Hutchins last night following a standoff with law enforcement officers. He is being held without bond. The exact charges that Ferrell is facing are unknown.

Ferrell’s arrest is linked to Monday’s early morning fatal shooting of 58 year old USPS truck driver Tony Mosby, who died after being shot in his truck while driving along eastbound I-30. Police found Mosby deceased inside his truck when they arrived on the scene.

Because Mosby was a federal employee, Ferrell will likely face federal charges. Ferrell is slated to appear in Federal Court today.

The U.S. Postal Inspectors and the F.B.I. aided Dallas Police in the investigation into the homicide.

On Monday night, the USPS offered a $50,000 reward for information that led to an arrest for Mosby’s murder.
