Idaho Statesman that Umphenour stayed with the couple at Henderson’s cabin a decade ago.Thompson — who had met Henderson online and moved from Washington State to Idaho to live with him in 2006 — said Umphenour, who was about 18 years old at the time, asked to stay with the couple because his family’s camper didn’t have a lot of space and he didn’t get along with his father.After a month, the couple kicked him out when he attempted to take control of the couple’s home and frequently talked about shooting people who disrespected him.“He had a volatile temper, which was frightening,” Thompson told the Statesman. “He would just explode all of a sudden, so it was like, ‘No we can’t have this here.'”Thompson says he never saw Umphenour after the couple kicked him out.
Around 2018, Thompson — who had grown tired of living in Idaho, especially as a gay man — left the cabin and lived in Orofino for some time.About a month ago, Thompson learned from Henderson that Umphenour had hiked up to the cabin and visited with Henderson for about an hour.Thompson said he didn’t think much of Umphenour’s visit at the time, but became concerned after learning about the 28-year-old’s recent role in helping break Meade out of custody.
After he couldn’t reach Henderson, Thompson called the Clearwater County Sheriff’s Office and asked them to do a welfare check.
Deputies found Henderson’s body around 8 p.m., though the Clearwater County Coroner’s Office estimated he had been killed about seven hours earlier.According to Idaho State Police, during their escape, the men encountered James Mauney while he was walking his dogs, took him to a remote area, and killed him before driving off in his Chrysler Pacifica.They drove to Henderson’s house and killed him, leaving Mauney’s dogs at the scene and setting out for Filer, Idaho, where they met up with 52-year-old Tonia Huber, reports Pullman Radio.An FBI agent saw Umphenour leave a residential neighborhood in Filer.
