Police in Alaska say a couple and their two young children who were found shot dead at their home in Anchorage last week died as a result of a murder-suicide carried out by the mother's boyfriend.

In a statement released Thursday, investigators said that evidence points to Curtis Young III, 24, shooting and killing his girlfriend, 27-year-old Desiree Gonzales, and their children, 4-year-old Zaiden Young and 17-month-old Zarielle Young, before turning the gun on himself.

'While the investigation is still [ongoing], with lab results pending, the evidence supports the theory that this was a contained scene and that this was a murder/suicide,' said Police spokeswoman Anita Shell in a statement.

Earlier, authorities had called the deaths an isolated domestic violence incident but stopped short of saying they suspected a murder-suicide.

A relative who went to check on the family at their apartment in Alaska's largest city found the four dead from gunshot wounds May 13.

The children's father usually dropped Zaiden and Zarielle off at their grandparents' home in the mornings before the grandmother took them to the babysitter, Police Sgt. Mike Couturier said during a press conference last week.
