On the evening of November 23, 2013, 23-year-old Braydon Aldinger and 26-year-old Derek Ferree were shot and killed in the 500 block of West Mason Avenue in York, Pennsylvania. Court documents say the encounter began with a planned heroin transaction that allegedly turned into a robbery and ended in the double homicide.

Investigators named three suspects tied to the incident: 22-year-old Laquan Anderson Pierrelouis (known as Q), 21-year-old Dejerek Basil Smallwood (known as Diego), and 22-year-old Arianna Tavares. Smallwood was arrested in December 2013 and charged with criminal homicide and conspiracy to deliver heroin. An arrest warrant was issued for Pierrelouis, who was described as a primary suspect in the shootings; Tavares was charged with conspiracy to deliver heroin for her alleged role in arranging the meeting.
