WEATHERFORD, Texas (AP) — Authorities say a Texas woman told investigators that she left her 2-year-old daughter and 16-month-old son in the hot car where they died last month to teach the girl a lesson, and that they didn't lock themselves in, as she initially said.

Twenty-four-year-old Cynthia Marie Randolph was jailed Friday on two counts of causing serious bodily harm to a child.

Parker County sheriff's officials say she told investigators Friday that she found the kids playing in the car May 26 and then closed the door and left them inside when the 2-year-old refused to come out.

She acknowledged going back into the home west of Fort Worth, smoking marijuana and then napping for two or three hours.

Temperatures reached the mid-90s that day.

Online jail records don't list an attorney for her.
