Christian Centano, 20, was found with a gunshot wound near McAllister and Larkin streets in San Francisco at about 2:22 a.m. on May 4, 2017. Paramedics transported him to San Francisco General Hospital, where he died from his injuries.

San Francisco police arrested two Daly City residents the next day in the 100 block of Leavenworth Street: Windell Lightle, 34, and Christiana Bryant, 31. Both were charged with murder and conspiracy; Lightle faced additional drug-related charges. Both were held without bail.

The case became part of the city’s violence statistics and proceeded through the legal system. What can anyone who knew Christian or witnessed activity near McAllister and Larkin that night add to the record?
