FORT MYERS, FL -- We're learning more about a Colorado mother who was arrested in Lee County for the deaths of her two sons.
She was arrested at her mother's house in North Fort Myers and is now at the Lee County Jail.
In a court appearance Thursday, Heather Holesapple-Jensen didn't fight extradition to Colorado. Last November her two children died from hyperthermia. Colorado authorities say the mother left them in her SUV for 40 minutes with the heat on, while she was having sex in a friends truck.
2-year old William died at the scene and 4-year old Tyler died in the hospital 6 days later.
"They were some beautiful, bright, smart little babies," said family friend Kimberly Owens.
Family friends say it was a common for Heather to leave the kids with someone else or alone.
"She'd show up and be like hey can you watch my kids for 30 or 45 minutes while I go run an errand, and four or five of six hours later, she might show back up," said another family friend.
The family was already dealing with tragedy after Holesapple-Jensen's husband, Eric, died in a car crash nearly a month before their children died.
Prosecutors expected to file charges weeks ago but the coroner's office called the deaths accidental.
with only three other hyperthermia court cases in the past 15 years, the state needed more time to prepare.
"That caused me to take a step back and re-evaluate and be as careful as i could," said Mesa County District Attorney Pete Hautzinger.
Now Holseapple-Jensen faces charges of negligent homicide along with two counts of child abuse resulting in death.
"I think she deserves a lifetime in prison. I'm a mother, how do you hurt that," said Owens.
