Troopers say Zachary A. Macintosh, 29, of Point of Rocks, Md., was pronounced dead at the scene.
The accident happened just before 1 p.m. Thursday in front of Hendershots Sporting Goods.
Lt. Michael Fluharty, who is the commander of the Hagerstown barrack, was conducting patrol in the area of Rt. 40 at Beverly Road near Hagerstown when he observed a 1999 Suzuki GSXR-750 speeding down the roadway at 75-85 mph in a 45 mph zone.
Lt. Fluharty activated his emergency lights and attempted to stop the motorcyclist, later identified as Macintosh.
Troopers say the motorcyclist continued down the roadway at a high rate of speed eastbound on Rt. 40, running a red light at which time Lt. Fluharty turned off his lights and lost sight of him.
Minutes later, police say Macintosh lost control of the motorcycle as he turned a curve, left the roadway and was ejected from the bike.
He sustained serious head injuries and died on the scene.
The investigation is ongoing, police say.
