Authorities identify the victims and say two exchanged gunfire while a third was shot at close range.
TEMPLE HILLS, Md. — Prince George’s County police on Monday announced the arrest of a 39-year-old man in a triple killing outside a banquet hall, outlining a fast-moving gunfight that began during a birthday celebration and ended with three men dead in the parking lot.
The case has drawn intense attention because it unfolded at a well-known event space along St. Barnabas Road and involved multiple guns, surveillance footage and a suspect captured in another state. Officials named the victims as Ronez Proctor, 27, of Waldorf; Pierre Davis, 33, of Washington; and Kevon Medley Williams, 26, also of Washington. Investigators said the suspect, identified as Antonio Lancaster of the Landover area, faces murder charges in Proctor’s death while detectives allege Davis and Medley Williams killed each other during an exchange of gunfire.
Police Chief George Nader said officers were called around 2 a.m. Saturday as people poured out of Irving’s Banquet Hall following a birthday party. Charging documents say video shows Lancaster firing first toward Medley Williams and Proctor while Davis stood beside him. Medley Williams then drew a gun and traded shots with Davis, according to investigators, striking each other as bystanders ducked between cars. Proctor tried to help Medley Williams amid the chaos and fell during a struggle with others in the crowd, the documents state.
Detectives said Lancaster walked up to Proctor and fired at close range before fleeing. Police recovered two handguns at the scene and are searching for a third firearm that evidence suggests was used during the crossfire. A motive for the initial dispute remains unclear. Lancaster was arrested in Fairfax County, Va., and is awaiting extradition to Prince George’s County for a bond hearing and further proceedings. Investigators said they are reviewing additional camera footage from nearby businesses and interviewing guests who left before officers arrived.
County leaders moved quickly to address safety at nightlife venues. Officials said Irving’s Banquet Hall has been shut pending a hearing after inspectors cited missing or inoperable security cameras and a lack of a formal security plan. “Having establishments open that late at night without security is a problem,” State’s Attorney Aisha Braveboy said, adding that the county expects cooperation from venue owners to prevent violence. The county reported a significant drop in homicides last year, but several shootings in the first days of 2026 have tempered that progress.
What happens next includes extradition of the suspect to Maryland, filing of formal charges in district court, evidence testing on recovered weapons, and scheduling of initial court dates. Prosecutors will decide whether to present the case to a grand jury as police continue to examine ballistic results and compare casings with surveillance timestamps. Regulators plan a separate public hearing on the hall’s operating status, cameras and staffing, with findings due later this month, officials said.
Neighbors described a loud burst of shots followed by cars speeding from the lot. “It was like a string of pops, then screaming,” said Alicia Bennett, who lives nearby. A partygoer who declined to give his name said an argument started inside and spilled outside after security moved people out. On Monday, a small memorial of candles and balloons sat near the curb as workers swept glass from the pavement and a tow truck hauled away a riddled sedan.
As of late Monday, police said the suspect remained in Virginia custody pending extradition. The next public update is expected after a bond review and once ballistics testing on the recovered guns is complete later this week.
