On the evening of Friday, May 11, 2018, 17-year-old Sandrea Williams stood in the driveway of her family home on the 300 block of North Simpson Street in West Philadelphia when two gunmen opened fire into a group of young people. At least 23 rounds were fired; Sandrea was struck and killed. Two other teenagers, a 17-year-old male and a 15-year-old boy, were wounded and survived. Sandrea’s mother was sitting on the front steps nearby and witnessed the shooting.

Sandrea was a young Black woman who emigrated from Jamaica at age five and had plans to join the military. Investigators later determined the attack stemmed from a feud between two rival groups in West Philadelphia and believe the gunmen were targeting members of a rival group who frequented the area; Sandrea was an innocent bystander. The inquiry involved ballistic evidence, cellphone forensics, and social media analysis.

What can readers who were in that neighborhood on May 11, 2018, or who knew Sandrea, add to this account?
