Authorities on Wednesday confirmed that a body found at the home of a former Washington state police officer who killed his ex-wife before fleeing to Oregon, where he died of a self-inflicted gunshot wound, was that of a 17-year-old girl with whom he had a baby. Elias Huizar, 39, a former police officer in Yakima, went on the run Monday afternoon after killing two people, including his ex-wife, Amber Rodriguez, 31, whom he shot eight times outside a West Richland elementary school in front of their 9-year-old son and other witnesses, police said. Rodriguez had recently obtained a protection order against Huizar.
