Amber Therese Jackson, 25, was shot to death on May 16, 2018, in North Philadelphia. Officers responding around 5:15 p.m. to a residence on the 1500 block of West Oakdale Street found Jackson on the second floor with a gunshot wound to the head; she was pronounced dead shortly after their arrival.

Jackson was active in advocacy against gun violence; her family described her as outgoing and lovable and believed she was safe at home. Authorities identified 21-year-old Khaleem Martin as the suspect and charged him with murder. Martin, described as 6 feet 2 inches, 180 pounds, with brown eyes, black hair, tattoos around his eyebrow area and a Jack Skellington forearm tattoo, surrendered to authorities on May 18, 2018, after being publicly identified. Family members noted Martin had earlier been arrested on aggravated assault and weapons charges in February 2018.
