Police have appealed for help finding a person of interest, after a gay activist was killed in San Francisco.
He was one of the organisers of the first Kalamazoo Pride festival in his Michigan hometown, and a supporter of the Kalamazoo Gay and Lesbian Resource Centre.
The video, released by San Francisco Police Department, shows a white man in his 20s or 30s wearing a grey hoodie with a red hoodie underneath.
Anyone with information about the man should contact the San Francisco Police Department.
