Maryland State Police Investigating Triple Fatal, Two-Vehicle Crash in St. Mary’s County

News |

(MECHANICSVILLE, MD) – Maryland State Police are continuing to investigate a fatal two-vehicle crash that occurred on April 24, 2025 in St. Mary’s County. 

The driver of a GMC Envoy, identified as Jean Gagnon, 59, of Mechanicsville, Maryland, was pronounced deceased on the scene. The driver and passenger of a GMC Canyon, identified as Casper Bradbury Sr., 92, and Norma Bradbury, 90, both of Mechanicsville, Maryland, were flown by Maryland State Police Aviation Command to MedStar Washington Hospital Center in Washington, D.C., where they were later pronounced deceased. 

At approximately 5:58 p.m., troopers from the Maryland State Police Leonardtown Barrack responded to the area of Maryland Route 235 (Three Notch Road) at Mt. Zion Church Road for a report of a two-vehicle crash. The preliminary investigation indicates that the GMC Canyon, operated by Bradbury, was attempting to make a left turn from southbound Rt. 235 onto Mt. Zion Church Road and failed to yield to the Envoy, operated by Gagnon, traveling northbound on Rt. 235, subsequently causing the Envoy to strike the passenger side of the Canyon. 


Deputies from the St. Mary’s County Sheriff’s Office and personnel from the Maryland Department of Transportation State Highway Administration assisted with road closures, which lasted for approximately three hours.

The Maryland State Police Crash Team is leading the investigation, which remains active and ongoing.
