A man has killed his ex-girlfriend's parents and held her younger brother hostage in an apparent revenge attack after their relationship ended.
Mirza Tatlic, 24, was eventually shot dead in a standoff with police at the San Jose home belonging to the parents of his ex, Rachel Prabhu.
He and Ms Prabhu's relationship ended last year but Tatlic appeared not to have got over the break up, comparing her to the devil in rambling Instagram posts.
Tatlic went to Prabhu's family home on Wednesday night. Prabhu, who lives in another state, was not there.
