Randolph faces two first-degree felony counts of injury to a child causing serious bodily injury.
Randolph told the police her children had been inside the auto "no more than an hour". Randolph told investigators that she left her 2-year-old daughter and 16-month-old son in a hot auto where they died May 26, 2017, to teach the girl a lesson, and that they didn't lock themselves in, as she initially said, according to sheriff's officials. So she shut the door to teach them a lesson, according to deputies.
Randolph said that after she closed the auto door on her two children she went inside her residence and smoked marijuana, then took a two-to-three hour nap, according to a news release from the Parker County Sheriff's Office.
But when she was arrested Friday, police said Randolph admitted to officers that she locked the children inside the auto on objective.
Police have arrested a Texas mother after she allegedly left her two young children in a hot vehicle as a form of punishment in late May.
The Fort Worth Star-Telegram reported that the Parker County Sheriff's Office stated in a press release that, after Randolph went inside the house to smoke marijuana, she took a nap lasting two to three hours. The children were pronounced dead at 4:33 p.m.
Parker County Sheriff's Department investigators arrested Cynthia Randolph after admitting that she left her kids in the vehicle to "teach them a lesson".
The sheriff's office said Randolph told them she found her children playing inside her auto at about 12:15 p.m. and ordered her daughter out of the vehicle using profanity.
No bond has been set yet for Randolph, and it is not clear whether she has an attorney.
A ruling on the cause and manner of death in each child is pending, according to the medical examiner's website.
A 16-month-old boy was also left in the vehicle, which likely reached a temperature of nearly 100 degrees while both children were inside.
On Friday, the Texas Rangers and a Dallas-based senior federal special agent conducted an interview with Randolph, where she implicated herself in the deaths of her children.
