The investigation continues into an officer involved shooting early Tuesday morning on Interstate 64 near Mount Vernon, in which an Illinois State Police trooper was shot.
At approximately 3:00 a.m. on I-64 eastbound at mile post 72, an ISP Trooper stopped to assist a stranded motorist on the right shoulder.
The Trooper encountered 23-year-old Brandon Griffin of Albuquerque, New Mexico and a female passenger in the vehicle.
A second ISP Officer arrived for routine assistance a short time later.
Eventually, an altercation occurred which led to gunfire between Griffin and a responding officer.
A 16-year ISP officer suffered serious, but non-life threatening, injuries after being shot during the altercation and is being treated at a regional hospital.
Griffin was pronounced dead on the scene. The other Trooper and female passenger were uninjured.
