Mariah Thomas, 28, pleaded guilty to endangering the welfare of a child resulting in death and was sentenced to 13 years in prison after the February 9, 2024, death of her one-month-old daughter, Za'Riah Mae Thomas. Prosecutors dropped an initial first-degree murder charge as part of the plea agreement. Investigators recovered evidence of thermal injuries and a burned blanket; a relative's statement that Thomas said she had accidentally put the baby in an oven figured centrally in the investigation. The sentence includes credit for time already served and formally closes the criminal case more than two years after the infant's death.

Mariah Thomas, 28, has been sentenced to 13 years in prison after pleading guilty to endangering the welfare of a child resulting in death in the case of her one-month-old daughter, Za'Riah Mae Thomas. The plea deal came after prosecutors dropped an initial first-degree murder charge in the February 9, 2024, incident at a Kansas City home that left the infant with severe burn injuries.
What Happened
Kansas City police were called to a residence on February 9, 2024, after a report that an infant was not breathing. Responding officers found Za'Riah with extensive thermal injuries; she was pronounced dead at the scene. According to court documents and a relative's account, a male family member had left Thomas and the baby alone earlier that day. He later returned after Thomas called and said something was wrong.
The relative reported smelling smoke and initially finding the infant in a crib. He told investigators Thomas allegedly said, "I thought I put Za'Riah in her crib and I accidentally put her in the oven." That statement was included in the probable cause affidavit and became a central element of the investigation.
Evidence and Investigation
Investigators later located the infant in a car seat in the living room. Za'Riah had thermal injuries across her body; her onesie appeared to have melted onto her diaper, and a burned baby blanket was recovered from the home. Thomas declined to speak with detectives when questioned, according to reports.
Charges, Plea, and Sentence
Thomas was initially charged with first-degree murder. Prosecutors ultimately reached a plea agreement in which the murder charge was dismissed and she pleaded guilty to endangering the welfare of a child resulting in death. On September 22, a Jackson County judge sentenced Thomas to 13 years in the custody of the Missouri Department of Corrections. She will receive credit for time already served.
Community Reaction and Official Statements
Neighbors described the event as shocking. Corrine Foreman told local media she heard sirens and saw a baby carrier moved between the house and an ambulance. Amber Morgan, another neighbor, said she was in disbelief that a child had died nearby.
Then-Jackson County Prosecutor Jean Peters Baker publicly thanked first responders and prosecutors who handled the case, saying, "We acknowledge the gruesome nature of this tragedy and our hearts are weighted by the loss of this precious life. We trust the criminal justice system to respond appropriately to these awful circumstances."
Case Closure
With the guilty plea and sentencing, the criminal case has been brought to a close more than two years after Za'Riah's death. The case underscores the heavy responsibility caregivers bear for an infant's safety and the severe legal consequences when a child's welfare is endangered.
