John Gerald Williams, 24, was shot multiple times in downtown Seattle on March 19, 2015, and later died at a local hospital. Police linked his killing to an ongoing feud between two street gangs: Williams was identified as a leader of the Low Profile gang, and investigators believe members of the rival Deuce 8s targeted him.

His death was described as a flashpoint in a cycle of retaliatory violence. Authorities say a subsequent drive-by shooting intended for a Deuce 8s member killed a one-year-old girl; DeMartrae Kime, a close friend of Williams and a Low Profile member, was later arrested and charged in that retaliatory killing. As of this account, no suspects have been publicly identified or arrested in the murder of John Gerald Williams, and the case remains unsolved.

Are there witnesses or information about Williams’ movements in downtown Seattle on March 19, 2015, that could help investigators?
