Nassir Day was 25 when he was killed while working as a security guard at an office building on the 5200 block of Old York Road in Philadelphia’s Logan section. Described by family as a gentle giant who loved his job and his budding family, Day was at his post on the morning of October 1, 2021, when 59-year-old Wayne Dorylis entered the building armed with three homemade spring-shot style guns and a large knife. When Day confronted Dorylis on the first floor, Dorylis shot him once in the head; Day was pronounced dead at the scene. His actions were credited with saving others in the building.

Dorylis then went to the third floor, where the administrative offices of Pathways to Housing were located. Witnesses heard more gunshots but no additional injuries were reported. Police found Dorylis on the third floor holding a large knife; he complied with commands and was taken into custody. Investigators said Dorylis held a grudge against the agency, had previously threatened staff, and had a history of arrests. Dorylis was charged in the attack. If anyone knew Nassir Day or has information about that morning, please share what you know.
