5 and 7 year old Utah children shot and killed by police officer father

A family tragedy in Utah resulted in a police officer shooting his 2 young children, his wife, mother-in-law and himself:

A 34-year-old officer with a small Utah police department shot and killed his wife, mother-in-law and two young children and turned the gun on himself, authorities said Friday. (...) 

Spanish Fork Lt. Matthew Johnson said the couple had been experiencing marital problems in the past few months, but co-workers say Boren appeared upbeat and didn't show signs of distress before the killings.

"There were no warning signs," Johnson said, adding that police had never been called to the home. "This was a total shock to everyone." (...) 

The five deaths come just days after another Utah murder-suicide that left three people dead.

Kyler Ramsdell-Oliva, 32, fatally shot her two daughters, 13-year-old Kenadee Oliva and 7-year-old Isabella Oliva, on Tuesday evening before killing herself at their home in Syracuse, police said.

The murder-suicide happened a day after the Ramsdell-Oliva's fiance packed up to move out of the house, authorities said
