http://abcnews.go.com/US/1985-washi...-couple-solved/story?id=16746875#.T_ylFeuRpXU July 10, 2012 Washington state officials have apparently solved the 1985 cold-case homicide of an elderly couple with an arrest that fulfills a grieving son's promise to his parents. Wilhelmina "Minnie" Maurin and Edward "Ed" Maurin's dead bodies were found Christmas Eve 1985. They had been shot to death and dragged into a wooded area. "At their funeral, I laid my hand on their casket and I said, 'I will find out who did this,'" the couple's son, Dennis Hadaller, said at a news conference Monday. A team of investigators from the Lewis County Sheriff's Office in Chehalis, Wash., was dispatched to Alaska July 8 to make an arrest in connection to the slayings.
