A Missouri mother who allegedly killed her 1-month-old by placing the baby in a hot oven has been charged with felony child endangerment, authorities said.

Mariah Thomas, 26, allegedly said that she accidentally placed her infant daughter in the oven instead of her crib when she was putting her down for a nap Friday, according to court documents obtained by HuffPost.

Kansas City Police officers responded to Thomas home in Kansas City , where she lives with her parents, after receiving a 911 call at around 1:30 p.m., according to a probable cause affidavit. The baby had apparent burn wounds and was pronounced dead at the scene by firefighters.

I thought I put [the baby] in her crib, and I accidentally put her in the oven, Thomas father said she told him, according to the affidavit.
