A Kansas City mother has been charged with a felony after she allegedly placed her newborn baby inside an oven, killing her.

Mariah Thomas, 26, said the infantā€™s death was a mistake, saying she thought sheā€™d put the one-month-old in her crib for a nap on Friday, according to a probable cause affidavit obtained by The Independent.

However, she had actually ā€œaccidentally put her in the oven,ā€ she claimed.

Police responded to the womanā€™s home after a 911 call reporting a ā€œnon-breathing infantā€.

There, emergency responders found the one-month-old baby, named Zaā€™Riah, with burn wounds and wearing melted clothing. She was declared dead at the scene.

Ms Thomas was arrested and charged with endangerment of a child resulting in death.

A close friend of Ms Thomas, who spoke anonymously to The Daily Beast, said she doesnā€™t believe her friend wanted to kill her newborn daughter.

ā€œMariah has been dealing with mental illnesses since a child,ā€ the friend said, adding that she stopped taking her medication when she got pregnant.

In the month since giving birth, her mental health worsened, the friend said. She felt lonely, and spoke about feeling like people didnā€™t care about her ā€” only her baby.

ā€œShe thought everyone only likes her because her daughter was born, and she didnā€™t like that at all,ā€ the friend said. ā€œShe wanted everyoneā€™s attention, too, just like Zaā€™Riah was getting attention.ā€

Even so, Ms Thomas loved her daughter and motherhood, the friend said.

ā€œShe didnā€™t mean to hurt her baby,ā€ she said. ā€œShe loved her baby dearly.ā€

Now, Ms Thomas is facing between 10 and 30 years in prison on the charges.

Jackson County Prosecutor Jean Peters Baker thanked the first responders and prosecutors who responded to the harrowing scene.

ā€œWe acknowledge the gruesome nature of this tragedy and our hearts are weighted by the loss of this precious life,ā€ Ms Baker said. ā€œWe trust the criminal justice system to respond appropriately to these awful circumstances.ā€
