JACKSON, Mississippi (AP) ― A Mississippi mother was arrested Wednesday in the death of her 3-year-old son after authorities said they found the child’s burned body in an oven.

Washington County Coroner Methel Johnson said police found Tristan Robinson’s body inside the electric oven at his mother’s apartment shortly after midnight. Johnson said the child had been burned in the oven, but an autopsy was ordered to determine whether he died before or after being put there.

Greenville Police Chief Freddie Cannon said Terrie A. Robinson, 24, was charged with murder. She was to be arraigned Thursday.

Johnson said the child’s body was still warm when it was removed from the oven.

“This is a really sad moment for me. I’ve seen a lot of things, but this is one that will stick in my memory for a long, long time,” Johnson said.

There appeared to be some trauma to the boy’s head, Johnson said, and that could have happened before he was placed in the oven.
