On Friday, May 30, 2025, at approximately 1:15 p.m., deputies from the St. Mary’s County Sheriff’s Office responded to a report of a two-vehicle collision in the 25000 block of Mechanicsville Road.

 

Upon arrival, deputies determined that a 2018 Toyota Highlander, operated by Marjorie Swann Boyers, 79, of Chaptico, collided head-on with a 2013 Chrysler 200, operated by Megan Nicole Rowley, 31, of Mechanicsville. A juvenile passenger was also in the Chrysler at the time of the crash.

 

Boyers was pronounced deceased at the scene. Rowley and the juvenile were transported by air to an area trauma center and remain in critical condition.

 

Due to the severity of the incident, the St. Mary’s County Sheriff’s Office Collision Reconstruction Unit was requested and has since assumed the investigation.

 

Preliminary findings indicate that Boyers was traveling south on Mechanicsville Road when, for unknown reasons, her vehicle crossed the center line and entered the path of Rowley’s vehicle.

 

At this time, speed and driver impairment are not believed to be contributing factors.

 

Anyone who may have witnessed the collision or has video footage of the incident or events leading up to it, and has not yet provided a statement, is asked to contact Corporal Vincent Pontorno at 301-475-4200, ext. 2337, or by email at Vincent.Pontorno@stmaryscountymd.gov.
