On the evening of April 4, 2023, Marcus Anthony Day, 26, of Leonardtown, was shot and killed in the parking lot of a Sheetz convenience store on Old Great Mills Road in Great Mills, Maryland. Deputies from the St. Mary’s County Sheriff’s Office responded at about 10:37 p.m. after reports of gunfire; a short time later MedStar St. Mary’s Hospital reported a man had arrived with multiple gunshot wounds. That man was Marcus Day, who later died of his injuries.

The investigation led to multiple arrests over the following months. On May 5, 2023, a 15-year-old male from Lexington Park was arrested in King George County, Virginia, and charged as an adult with first-degree murder and related offenses; his identity has not been released due to changes in Maryland law. On November 20, 2023, a grand jury indicted 19-year-old James Jerome Adams Jr. of Great Mills and another individual who was a juvenile at the time; at the time of indictment the suspects were already incarcerated on unrelated matters.

A broader conspiracy to kill Marcus Day is described in court filings, with several individuals named in connection with planning the attack. Who saw or heard anything that night in the Sheetz parking lot, or who can add details about the people involved?
