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

Twenty-four-year-old Cynthia Marie Randolph was jailed on Friday, June 23rd on two counts of causing serious bodily harm to a child.

Parker County Sheriff's Office 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.
