Six people were injured, the gunman fled.
Police in the California city of Fresno are investigating a mass shooting at a party watching a football game on Sunday that left four people dead and at least six others injured. Five of them are in critical condition, police said.
Three people died at the scene, one died in the hospital, Fresno Deputy Police Chief Michael Reed said at a news conference late in the evening. Six other people were hospitalized, he said.
“Our hearts go out to the families of the victims of this incident,” Reed said. “This is senseless violence. We will do everything possible to find the perpetrators and bring them to justice.”
Shortly before 8 p.m. local time, a gunman entered the backyard and began shooting at an apartment building in southern Fresno, where about 35 people, including family and friends of the owners, had gathered to watch a football game, Reed said. After that, the rescue service received numerous calls from neighbors.
The suspect fled the scene and police were combing the area for witnesses. Authorities are also examining surveillance footage.
Police gave no further details about the shooting in the city 320 kilometers North of Los Angeles, limiting the information that the dead were between 25 and 35 years old.
Others injured at the party may have driven to the hospital on their own, police said, noting that some of the injured were taken to a nearby community medical center with gunshot wounds.
