Breontae Mosley, 17, was fatally shot during a sleepover at a friend’s home on McDowell Lane in the Lansdowne area of Halethorpe, Maryland, in the early morning hours of Tuesday, May 27, 2026. Police were called about 5:30 a.m. after two 911 calls from the residence — the first capturing what sounded like an argument and a command to put something down, the second reporting gunfire. Officers found Breontae in an upstairs bunk bed and he was pronounced dead at the scene.

Investigators concentrated on a person who was inside the house that night. Charging documents state 22-year-old Marquis Washington, the older brother of the host, was arrested and charged with first-degree murder and a firearm offense. A firearm was recovered from a backpack at the bottom of the stairs. According to the documents, Washington told police the voices in his head had gotten to him; his mother told detectives he had a history of mental illness, including multiple hospitalizations and prescribed medication. A judge ordered Washington held without bail pending further proceedings.

Breontae was described by family as a young man with an infectious smile who dreamed of becoming a rapper and entertainer. The community remains shaken and many questions about that night remain unanswered. If anyone has information about Breontae, the people he was with, or what happened inside the house, please come forward.
