Quamir Jones, a 25-year-old Philadelphia man known by the alias "YP SlumBoy," was arrested Thursday by U.S. Marshals in connection with the fatal shooting of the mother of his child last October. Jones faces charges including murder, tampering with evidence, and criminal solicitation regarding the death of 23-year-old Siani Smith.
According to the affidavit of probable cause, the incident occurred early in the morning on October 12 in the Eastwick neighborhood. Investigators state that Smith was sitting in the passenger seat of a vehicle parked on the 7400 block of Dicks Avenue when Jones approached the car shortly after 5 a.m. Following a brief exchange with the driver, Jones allegedly reached into the vehicle and fired a weapon, striking Smith. Police reports indicate he fired a second shot as the driver sped away to transport the victim to a nearby hospital, where she was pronounced dead.
Following the shooting, Jones allegedly contacted Smith’s mother, claiming a group of men had been outside her home and instructing her to collect shell casings to prevent them from being traced to a gun registered in his name. The affidavit notes that while Smith’s mother had heard gunshots earlier, she did not find any casings. Authorities later confirmed that Jones possessed a valid permit for a Glock 9mm pistol registered in Delaware County.
The U.S. Marshals Service of Eastern Pennsylvania apprehended Jones on the 200 block of E. Mermaid Lane in Chestnut Hill, ending a nearly three-month search. In a statement released following the arrest, the Marshals alleged that Jones is a member of the city’s "Blumberg" gang. Court records show Jones is currently being held without bail at the Curran-Fromhold Correctional Facility.
Judicial and Investigative Proceedings
The apprehension of Jones by the U.S. Marshals Fugitive Task Force underscores the interagency coordination required to locate high-priority violent offenders in the Philadelphia region. As the case moves to prosecution, the inclusion of tampering and solicitation charges suggests a legal strategy focusing on post-incident conduct as well as the homicide itself. The denial of bail indicates the court’s assessment of flight risk or community danger given the severity of the allegations. It is important to note that all individuals are presumed innocent until proven guilty in a court of law.
