Nineteen-Year-Old Charged in Death of Germantown Woman Following Rollover Collision

For Immediate Release: Thursday, January 8, 2026

Gaithersburg, MD - A 19-year-old has been charged in connection with a rollover collision that killed a Germantown woman last year.

The charges stem from a crash that occurred on Monday, July 21, 2025, at approximately 10:35 p.m., at the intersection of Great Seneca Highway and Mateny Road. Montgomery County Police 5th District officers and Montgomery County Fire and Rescue Services responded to the scene for a report of a rollover collision with ejection.

The investigation by the Collision Reconstruction Unit determined that Mary Elizabeth Moody, of Germantown, was driving a white 2018 Subaru and was attempting to turn left from southbound Great Seneca Highway onto eastbound Mateny Road when her car was struck by the driver of a black 2021 Mazda traveling northbound on Great Seneca Highway. The impact caused the Subaru to roll over, ejecting Moody from the vehicle.

Despite lifesaving efforts, Moody was pronounced dead at the scene. The driver of the Mazda, identified as 19-year-old Brody Richardson of Boyds, was transported to an area hospital with serious injuries.

CRU detectives determined that Richardson was at fault in the collision and that impairment and excessive speed were contributing factors. Evidence showed Richardson had consumed alcohol prior to driving. A blood sample obtained at the hospital and analyzed by the Maryland State Police Forensic Sciences Division revealed a blood alcohol concentration of 0.20. Investigators also determined Richardson had used marijuana before driving.

Vehicle data and scene analysis indicated Richardson was traveling approximately 94 miles per hour in a 55-mph zone as he approached the intersection.

Richardson surrendered on an outstanding warrant on January 6, 2026, and has been charged with manslaughter by vehicle due to gross negligence, negligent homicide by vehicle while under the influence, and other related offenses. He was released on a $10,000 personal bond.
