Deputies from the St. Mary’s County Sheriff’s Office executed an arrest warrant on Dmontre Montez Bush, 25, of Lexington Park, on Wednesday afternoon in connection with a November stabbing and robbery in Lexington Park.
Bush was taken into custody and transported to the Detention and Rehabilitation Center in Leonardtown, where he is being held pending a bail review on charges of armed robbery, robbery, first-degree assault, second-degree assault, and two counts of theft of $100 to under $1,500.
The arrest follows an investigation that began when deputies responded to a report of a suspicious incident on Spyglass Way in Lexington Park on Sunday, Nov. 16, 2025. Shortly afterward, deputies received a second call reporting a walk-in assault victim with stab wounds at the Bay District Volunteer Fire Department, also in Lexington Park. The victim reported that while meeting with an acquaintance, multiple suspects confronted, robbed, and assaulted him before he was able to escape, return to his vehicle, and drive to the firehouse for help. He was flown to a regional hospital, treated, and later released.
The case remains under investigation. Anyone with information is asked to contact Detective Kortnie Marsch at 301-475-4200, ext. 8179, or by email at Kortnie.Marsch@stmaryscountymd.gov.
