Man kills mother and two brothers
A man who had been in a business dispute with his two brothers shot and killed them, as well as one of their wives and his mother, before taking his own life, according to police in Phoenix, Arizona.
Sgt Trent Crump said the man's wife and two young children escaped from the home along with another woman when the gunfire broke out on Thursday afternoon.
Police are not yet identifying the four victims or the man who opened fire and later killed himself.
Sgt Crump said that the three brothers ran a company offering cars for hire and a restaurant.
He said there had been an ongoing dispute about the business, and the brother who opened fire said goodbye to at least one surviving family member earlier in the day.
