Parker County, Texas, police arrested Cynthia Randolph, 24, last week in connection with the deaths of her two children, Juliet, 2, and 1-year-old Cavanaugh.
Parker County sheriff's officials say she told investigators Friday that she found the kids playing in the auto May 26 and then closed the door and left them inside when the 2-year-old refused to come out. It is programmed to begin blowing if the vehicle reaches a certain temperature. According to investigators, when the two children refused to get out of the vehicle, Randolph made a decision to teach them a "lesson" by closing the door and leaving them alone in the auto.
Hot cars kill an average of 37 children each year, and 14 kids have already died in 2017. When she awoke, she found the children unresponsive inside the vehicle and broke the window to make it look like an accident, the statement said.

WFAA reports that Child Protective Services (CPS) had previous contact with Randolph before the children's death, but the details are now disclosed.
Randolph was charged with two counts of first-degree felony injury to a child causing serious bodily injury and booked into the Parker County Jail, where she remains with bail set at $200,000.
In an effort to keep kids safe, NBC News reports Representative Tim Ryan, D-Ohio, recently introduced the Hot Cars Act of 2017.
Hopefully, that bill will result in a law that not only prevents heartbreaking accidental deaths from hot cars, but also keeps parents with criminal intentions from being able to claim they were unaware they had a child in the auto.
