On the night of Dec. 22, 2006, Tuvera, 28, tried to take 33-year-old Marlon Ruff into custody in the Sunset District. Ruff had escaped from a Northern California state correctional work camp the year before.
Tuvera, a four-year veteran who worked out of the Taraval station, chased Ruff into the garage of a home, where Ruff then shot and killed him.
Ruff was struck by return fire from a second officer and then fatally shot himself.
Wednesday’s vigil will take place from 8 p.m. to 9 p.m. at the Taraval Station Community Room, 2345 24th Ave.
