A US police officer who is believed to have killed his wife, mother-in-law and two children before turning the gun on himself was experiencing marriage problems in the months leading up to the shooting, his boss said.
There were no red flags - everything about him was outstanding. We're a small department, our families are one big family so we knew his entire family as well. It's just a tremendous shock.
I was aware that there had been a recent period of separation, but I am not aware of any violence in the past or anything like that.
His wife Kelly was a friend of mine and a friend of my wife so anything major that would have happened I probably would have known about.
I know as a family they went to Disneyland over the Christmas holidays.
– Chief Cody Cullimore, of Lindon City Police speaking to The Salt Lake Tribune
Officials said they did not find a suicide note at the crime scene.
