GRAND JUNCTION, Colo. (KUSA) - The mother of the two boys who died of hyperthermia in Mesa County was arrested on Wednesday in Fort Myers, Florida, after authorities outlined a series of lies she spun in an arrest affidavit made public in the case.
Heather Jensen is facing two counts of child abuse resulting in death, two counts of criminally negligent homicide, and one count of false reporting to authorities.
Authorities say 2-year-old William Jensen and his 4-year-old brother, Tyler, became fatally overheated six weeks ago in Jenson's 95 Toyota 4-runner. William died that day of hyperthermia, Tyler died nearly a week later.
In an arrest affidavit released Wednesday, Sheriff's deputies report having a difficult time piecing together the events that led up to the boys' deaths because Jensen's story changed several different times.
Court records show Jensen first told authorities that she left the boys in a running car to talk to a friend after playing in the snow near Powerhorn Ski Resort. She first told authorities the boys were left alone in the car for just 10 minutes. Later she admitted the boys were left alone in her vehicle for more than 90 minutes.
After a series of interviews with Jensen, the friend she met with at Powderhorn, and several others who knew Jenson and her boys, deputies say they've come up with a very different story about what led to the children's deaths.
Investigators say Jensen was having an affair with one man while she was married to the boy's father. That man moved in with Jensen and her boys two days after Eric Jensen died in a car accident in October of 2012. Investigators say she was meeting with a second man in Powderhorn when she locked the kids in the car on Nov. 27, 2012.
Investigators say the man she was meeting at the closed ski resort was Colten Childers. He says the boys never got out of the car that afternoon and were asleep when she parked her vehicle next to his.
According to the document, Childers says he and Jensen first talked outside and then moved into his truck when it got chilly. Childers says before they got into his truck Jensen started her vehicle to "warm it up for her kids."
Some time passed, according to the affidavit, before Jensen got out of Childers' truck to check on the boys after seeing her son Tyler open his door. That is when Childers says Jensen gave the 4-year-old her cell phone to play with before she locked the doors of the 4runner and got back into his truck.
Once she returned to his truck, Childers told investigators he and Jensen had "sexual relations" in the back seat.
Investigators say they think the boys were alone in the running car for 65 minutes with the heat on. Tests conducted on Jensen's vehicle show that the temperature jumped to 114 to 123 degrees after letting it run 30 minutes with the heat on high. After an hour the temperature jumped to 127 to 145 degrees.
Jensen is being held in Florida on a $150,000 bond. Mesa County authorities are trying to extradite her to Colorado.
