The couple's 10-year-old daughter called police just after midnight to say that her dad shot her mom. Police went to the home at 244 Niemi Rd., and were able to get the mom and several kids out of the house.
A SWAT team was called in, and found 30-year-old Miguel Angel Milian dead in a room upstairs.
His estranged wife, 27-year-old Chante Marie Milian, is in stable condition in a Portland hospital. She was shot once in the back, police said.
Police didn't say how Milian died, but they said he called a friend and said that he had shot his wife and was going to shoot himself.
None of the children were hurt.
