On Sunday, July 12, 2026, at approximately 12:45 a.m., Troopers from the Maryland State Police College Park Barrack responded to the area of Route 301 at Governors Park Lane for a report of a crash involving a passenger vehicle and a motorcycle.
The preliminary investigation indicates that a black Tesla Model 3 was attempting to make a left turn from Route 301 onto Governor’s Park Lane and failed to yield to the right-of-way of a Harley-Davidson that was traveling southbound on Route 301. The Harley subsequently struck the Tesla’s passenger side.
Investigators believe a third vehicle struck the Harley passenger after the initial crash and then left the scene. No further description of that vehicle is available at this time. Police are seeking the public’s assistance in locating the driver and vehicle. Callers with relevant information are urged to contact Sgt. Gore at 410-819-4753.
The operator of the Harley, identified as Matthew Eric Vowell, 48, and the passenger, identified as Krystal Ann Vowell, 47, both of Friendship, Maryland, were both pronounced deceased on scene by emergency medical services personnel.
The rear passenger of the Tesla, identified as Adriana Lanae Maxwell, 22, of Glen Burnie, Maryland, was also pronounced deceased on the scene by emergency medical services personnel. The driver of the Tesla was transported to a local hospital for treatment. Investigators believe the Tesla was operating as a rideshare service at the time of the crash.
The Maryland Department of Transportation State Highway Administration assisted with road closures, which lasted for more than four hours.
The Maryland State Police Crash Team is leading the active and ongoing investigation. Upon completion, the investigation will be presented to the Office of the State’s Attorney in Prince George’s County to determine whether charges will be filed.
