A Missouri mother, Mariah Thomas, pleaded guilty on Tuesday to first-degree endangering the welfare of a child resulting in death and was sentenced to 11 years in prison, resolving a case that began with the death of her 1-month-old daughter in February 2024.
The Jackson County court records indicate Thomas reached a plea agreement with prosecutors, who dropped a first-degree murder charge as part of the deal. She will receive no probation and has been credited for time already served. The incident occurred in Kansas City, Missouri, where Thomas’ infant daughter, Za’riah Thomas, was found deceased with severe burns.
Key developments in the case
- Plea and Sentencing: Thomas pleaded guilty to the lesser charge on Tuesday, finalizing a resolution that avoids a murder trial. The sentence was handed down by the Jackson County court system.
- Charges Adjusted: The original first-degree murder charge was dismissed as part of the plea agreement, according to court records.
Circumstances of the incident
On February 9, 2024, Kansas City police responded to a call reporting an unresponsive infant at a residence in Kansas City. Upon arrival, officers found Za’riah Thomas with apparent burns across her body. Fire department personnel pronounced her dead at the scene.
Investigators later stated that Thomas told authorities she had accidentally placed the infant in an oven instead of a crib while attempting to put her down for a nap. A family member corroborated this account, telling detectives that Thomas said, “I thought I put [her] in her crib and I accidentally put her in the oven.”
Police reported that Za’riah was wearing a bodysuit over a diaper, and her clothing appeared to have melted onto her skin. A baby blanket with significant burn marks was also recovered from the living room, according to the probable cause statement.
Legal and procedural details
The plea agreement specifies that Thomas will serve 11 years in the Missouri Department of Corrections, with no probation period. She has been held in the Jackson County jail since her arrest in February 2024. The dismissal of the murder charge was part of the negotiated resolution.
Background on the victim
Za’riah Thomas was identified as a 1-month-old infant. A family member described her as a “bubbly” baby who was smiling all the time prior to her death, according to reporting from local media.
