BALTIMORE (AP) — Authorities say an off-duty Washington, D.C., police sergeant was fatally shot while sitting in a parked car in Baltimore and a woman with him was injured.

Baltimore police said in a statement that officers found 40-year-old Tony Anthony Mason Jr. with gunshot wounds early Saturday morning. He died of his injuries at a hospital.

The Metropolitan Police Department in Washington said Mason, a sergeant, was a 17-year veteran of the force. Public information officer Sean Hickman referred all further inquiries to Baltimore police.

The second victim, a 43-year-old woman, suffered a gunshot wound to her leg and was taken to a hospital.

Investigators believe Mason and the woman were inside the car when an unknown suspect approached, began shooting and then fled.

No information about a motive was immediately released.
