Fatally Burned One-Year-Old Girl Was Placed in Oven by Her Sibling, Documents Say

The heart-breaking story of a Texas toddler found fatally burned took an even more horrific turn this weekend as authorities revealed that they believe the little girl's sibling placed her in an oven and turned it on.

Police believe 19-month-old J'zyra Thompson was left alone in her Houston home by her mother along with her two 3-year-old siblings and another child on Monday.

When Texas Child Protective Services spoke to the 3-year-olds, the siblings told them one of them had put J'zyra in the oven and made it "hot," according to documents obtained by KTRK.

The court documents say the siblings saw their little sister trying to kick the door as she lay in the hot oven.

Their mother performed CPR when she got home, but it was too late, according to court documents.

No charges have been filed against the mother or her boyfriend. However, documents indicated that authorities expect charges to be filed.

"There are concerns that the children were often left home alone and without adult supervision. CPS had prior involvement with the mother and her children," agency spokeswoman Estella Olguin told the AP on Friday.

A man who identified himself as the father of the 3-year-olds, Fredrick Price, told KTRK he'd be trying to get in touch with the mother of the children for months.

"It's very irresponsible, someone should have been here or I should have gotten a phone call, come and get my children," Price said.
