A black woman has been arrested 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. 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 is to be arraigned in Greenville, a city of about 35,000 residents in the Mississippi Delta. Johnson said the child's body was still warm when it was removed from the oven. 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. Officers found the body after responding to an emergency call, but the chief didn't want to release any details because of an ongoing investigation. Johnson said a little girl found in the home was placed in the care of the Mississippi Department of Human Services.
