On the night of December 18, 2016, 27-year-old Lindsay McCollum and 51-year-old Eddie Tennessee Tate were shot and killed while sleeping in a makeshift shelter at the corner of 16th Street and South Van Ness Avenue in San Francisco’s Mission District. Both victims, described as homeless, were inside a wooden box when an assailant approached and fired multiple shots. McCollum was declared dead at the scene; Tate died after being taken to hospital.

Lindsay’s mother, Carrie, has worked to keep her daughter’s memory alive, stressing that Lindsay—who struggled with addiction and homelessness—was a kind, talented person who loved animals, played piano and enjoyed reading as a child. The case remains unsolved; investigators and the community have increased a reward over the years, now totaling $200,000, in hopes someone will come forward.

Does anyone who knew Lindsay or witnessed activity near 16th and South Van Ness on December 18, 2016, have information to share?
