Mechanicsville, Md. — A head-on collision on Mechanicsville Road killed one person and critically injured two others on May 30, 2025, according to the St. Mary’s County Sheriff’s Office. The crash, reported at 1:15 p.m. in the 25000 block, involved a 2018 Toyota Highlander and a 2013 Chrysler 200. Authorities have launched an investigation to determine the cause.
Deputies arrived at the scene and found that the Toyota Highlander, driven by Marjorie Swann Boyers, 79, of Chaptico, had collided with the Chrysler 200, operated by Megan Nicole Rowley, 31, of Mechanicsville. A juvenile passenger was in the Chrysler during the incident. Boyers was pronounced dead at the scene. Rowley and the juvenile were airlifted to a regional trauma center, where they remain in critical condition.
The St. Mary’s County Sheriff’s Office Collision Reconstruction Unit is leading the investigation due to the crash’s severity. Preliminary findings suggest Boyers was traveling southbound when her vehicle crossed the center line for unknown reasons, entering the path of Rowley’s northbound car. Investigators have ruled out speed and driver impairment as contributing factors at this stage.

Anyone with information is urged to contact him at 301-475-4200, ext. 2337, or via email at Vincent.Pontorno@stmaryscountymd.gov.
