Gov. Bob McDonnell says a trooper involved in a shooting along Interstate 85 in Dinwiddie County has died.

McDonnell says 40-year state police veteran Master Trooper Junius Walker was shot while on duty on Thursday.

Virginia State Police spokeswoman Corinne Geller says Walker was shot multiple times around 1:30 p.m. He called for backup, and a trooper who arrived within two minutes saw a male suspect shooting into Walker’s car. The second trooper fired at the suspect, who fled into the woods on foot.

The suspect was arrested before 2 p.m. Charges are pending.

Geller says authorities are working to determine if another suspect was involved in the shooting, near the 45-mile marker.

A portion of the interstate remains closed while police investigate.
