A dispute inside a 7-Eleven in Silver Spring turned deadly in the early morning hours of September 23, 2018. Deon Christopher McDonald, 27 and a Hyattsville resident, was making a purchase about 3:52 a.m. when he got into an argument with the store clerk. A 44-year-old on-duty security guard employed by a contracted company intervened, the confrontation became physical, and it moved onto the sidewalk where the guard discharged his weapon and struck McDonald.

Police and paramedics found McDonald unresponsive with a gunshot wound; he was pronounced dead at the scene. Montgomery County Police Major Crimes Division opened an investigation and coordinated with the Montgomery County State’s Attorney’s Office. McDonald’s family said he was unarmed and had one arm in a cast and sling at the time. There have been no announced updates about charges or the final outcome of the prosecutor’s review.

If anyone witnessed the incident or has information about what happened inside the store or on the sidewalk, please share what is known.
