Police found him with multiple gunshot wounds shortly after 7:20 p.m.; he was pronounced dead at the scene. A Marine veteran who enlisted in 2011 after high school, Killian was remembered by friends and family as an easygoing, cheerful person who often lifted others’ spirits.

The motive for the killing remains unclear. His death came amid a larger wave of violence in Oakland that year, and family and friends organized a fundraising campaign to cover funeral expenses, underscoring the loss of a promising young life.
