Naked Woman Murdered with Screwdriver on I90 [UPDATE]

Early this morning a naked woman was found killed on the side of I90 near Ritzville with a screwdriver stabbed in her heart. A man says he stopped when he saw a man holding a 3 year old child on the side of the highway to see if they needed help. When he approached the man, the man with the child took off on foot. That is when the man who stopped saw the naked woman on the ground and called police.

Now reports say that authorities now think the woman was killed by 33 year old Manuel Argomaniz Camargo, the man who took off on foot. The victim was in her 20's and is the mother of the child at the scene. Camargo says he is the father and the family is from the Chicago area. I90 will be closed for several hours while the investigation is underway.
