Social justice activists from a group called Poder held a candlelight vigil for Bryan Carreño at the Santa Barbara County Courthouse on Wednesday night.
Carreño’s friends are upset he was fatally shot by Sheriff’s deputies on Sunday night after his family called 911 to get him mental health help.
Neighbors near North La Cumbre Road said they saw him jumping fences and entering homes.
Investigators said he had a large kitchen knife when they tried to take him into custody.
Organizers of Wednesday’s peaceful demonstration said Carreño joins a list of people who have died in similar situations.
Carreño, 26, is being remembered as an activist who was instrumental in the fight against a Santa Barbara gang injunction.
The Sheriff’s office has not released the names of the deputies involved.
