On the morning of November 1, 2020, a Halloween house party on Bristol Court in the Dale City neighborhood of Woodbridge, Virginia, turned deadly when an argument at the gathering escalated into a physical fight and a man produced a handgun. Twenty-five-year-old Frank Chineji Sapele of Arlington was fatally shot at the scene. Another partygoer, 24-year-old Christopher Alan Johnson of Alexandria, was also killed. Two other guests — a 23-year-old man and a 24-year-old woman — suffered serious but non-life-threatening injuries.

Prince William County detectives identified 26-year-old Karriem Angelo Jackson of Reston as the suspect after determining he had been involved in the initial altercation, was asked to leave, and then opened fire on attendees. Jackson was located and arrested by the U.S. Marshals Fugitive Task Force in Fairfax County on November 5, 2020. He was charged with two counts of second-degree murder, two counts of aggravated malicious wounding, and four counts of using a firearm in the commission of a felony. In August 2025 a jury found Karriem Jackson guilty of two counts of first-degree murder, two counts of aggravated malicious wounding, four counts of use of a firearm in the commission of a felony, and one count of maliciously discharging a firearm in an occupied building; sentencing was scheduled for December 5, 2025.

If anyone attended that party or has information about the events on November 1, 2020, please come forward.
