According to police, the crash occurred between 3 a.m. and 3:30 a.m. Tuesday on I-97 near Route 32 and Benfield Boulevard in the Millersville area.

Police said a preliminary investigation indicates Borgmann was the passenger in a street sweeper truck that was traveling northbound on I-97 when it entered the median, struck the guardrail and overturned.

Both men were reportedly ejected from the truck, and then Borgmann was struck by a vehicle—that left the scene—in the southbound lane.

Police believe Borgmann's body landed on the vehicle's hood since it was found more than 200 feet from the point of impact.

The vehicle that struck Borgmann may have extensive front end damage, most likely to the hood and windshield. The vehicle is missing a windshield wiper, which was recovered at the scene.

Anyone who witnessed the crash or may have been in the area at the time is urged to contact Maryland State Police at 410-761-5130.
