MIAMI — A man barged into a birthday party early Sunday, shot his estranged wife and three other people to death, then went home, set his truck and house on fire and killed himself, police said.

Witnesses described a chaotic scene that started when the man showed up uninvited at the party and told about a dozen people there that he blamed them for his wife leaving him, said homicide detective Ervens Ford.

Police did not release the victims’ names because other family members had not been notified. They said the man and his wife were married about four years, and they weren’t sure when she left him.
