Story summary

Mariah Thomas, 28, from Kansas City, Missouri, pleaded guilty on Tuesday to first-degree endangering the welfare of a child resulting in death. Three years after she was arrested and charged with murder following an incident where she placed her 1-month-old daughter Za'Riah Mae into an oven instead of her crib, Thomas will now serve 13 years in prison. The tragic event occurred on February 9, 2024, when emergency services were called to Thomas's home after a witness reported that the baby was not breathing properly. Police found the infant severely burned and later pronounced dead at the scene by the Kansas City Fire Department. Despite initial murder charges, prosecutors dropped these in favor of a plea deal for the lesser charge. The Jackson County Prosecutor, Jean Peters Baker, expressed regret over the loss, stating that "our hearts are weighted by the loss of this precious life."
