(Longview, WA)  --  A Longview man is facing charges, after being accused of killing his estranged wife and then trying to kill himself.  Cowlitz County sheriff's deputies say 73-year-old Cleon Moen will be arrested after he's released from a hospital, where he's being treated for carbon monoxide poisoning.  Moen is accused of killing Michelle Moen Sunday.  Cleon Moen was tried in November for assaulting his wife and shot himself in the courthouse parking lot after the trial ended in a hung jury.  He recovered from the wound.
