A man called 911 early Sunday morning to report that he had shot his son and daughter.
Puyallup Police say a 69-year-old man called police at 3:27 a.m. to say he had shot his adult son and adult daughter.
911 operators talked the man into putting his gun down and he surrendered to officers when they arrived at his home on the 1500 block of 5th Street SE.
Officers entered the home and found two people gravely injured from gunshots to the head in separate bedrooms of the house. Deputy Chief Dave McDonald say the two appear to have been shot in their sleep.
Police also found the man's wife, and two children under 10 years old, unhurt. Police believe the children belonged the male victim.
Both victims, a 43-year-old woman and a 46-year-old man, were taken to Tacoma General Hospital, where the woman later died, he said. The man was in "grave condition" condition, police said.
Their names have not been released.
Police have responded several times to the home for domestic violence-related disputes, McDonald said. Those incidents always involved disputes between adult family members, he said.
"I know they were frustrated," McDonald said about the grandparents.
A neighbor said police have responded before to deal with the couple's son.
"It was common to hear fighting with the son," said the neighbor, Beau Nye.
He said two young boys live at the house with the grandparents.
"They were playing all day yesterday," Nye said of the boys. "Chasing each other and laughing. They were having a great time."
