Middle River couple dead in murder-suicide as husband kills estranged wife and then himself

On June 16, 2025, at approximately 10:13 am, Anne Arundel County Police Officers responded to a report of a shooting at the Smith Bus Service located in the 1800 block of Bucklina Ave in Odenton. Upon their arrival, police located a woman suffering from a gunshot wound. Emergency Medical Service personnel responded and pronounced the 45-year-old woman dead at the scene.

During their investigation, detectives were able to obtain and view video surveillance of the fatal shooting. The video footage allowed detectives to identify the shooter as 48-year-old Trimall Stephenson, an employee at the bus service – and the estranged husband of the victim, Monyette Marie Stephenson.  

Both of the Stephensons are listed as being residents of Middle River, Maryland.

Trimall Stephenson was subsequently located by law enforcement at a rest stop in Hamilton, New Jersey. As Troopers from the New Jersey State Police approached his vehicle, Trimall Stephenson turned a gun on himself and ended his own life.

Next of kin of the victim and suspect have been notified. Anne Arundel County Police (AACOPD) Homicide Detectives are working with the New Jersey State Police on the investigation.
