Police were called to her home near Lake Weatherford on May 26 where Randolph told police she found her two kids unresponsive after being locked inside a vehicle. The incident was reported shortly after 4 p.m. when it was about 96 degrees.

Randolph initially said she was inside her home folding laundry and watching TV while her kids played in an enclosed back porch that was visible from the living room. She said about 20 to 30 minutes had passed when she realized her kids were “gone."

Randolph told police she sent more than half an hour looking for her kids and later found them locked inside her car. She said the kids got in the car on their own and locked themselves in. Both kids were pronounced dead shortly after 4:30 p.m. She told police her kids were not in the car for more than an hour.

Throughout multiple interviews, police say Randolph changed her story several times about what lead to the death of her children.

The Texas Rangers and U.S. Department of Justice Office of the Inspector General Dallas Field Office senior special agent conducted a final interview with Randolph on Friday, where she implicated herself in the role she played involving the death of her children.

Randolph confessed to police that around she found her children playing inside her car around noon and ordered her daughter out of the car using profanity. When the 2-year-old refused to exit the car, Randolph said she shut the car door to teach her daughter a "lesson," thinking "she could get herself and her brother out of the car when ready."

Randolph then told investigators she went into her home, smoked marijuana and went to sleep for two to three hours. Randolph implicated herself again when she told investigators she later broke the car window to make it look like an accident.

Randolph is charged with two first-degree felony counts of injury to a child causing serious bodily injury. She was booked into the Parker County Jail. Her bond has not been set.
