Police took a person into custody after a baby was stabbed, placed in an oven and baked at a home in western Mississippi.
Williams says the girl's grandmother is being held in the death but that charges hadn't been filed as of Tuesday morning, WTVA reported.
The child was found after a call around 7 p.m. Monday night at a house on Martin Luther King Drive in Shaw, Miss., according to WTVA.
Mississippi Department of Public Safety spokesman Warren Strain says police were called Monday night to a home in the town of Shaw.
"I've been from St. Louis to here and some of the most horrific scenes that I've seen in law enforcement involve children".
Sheriff Kelvin Williams said they thought the child had been stabbed and burned. Police are still unsure if she died before she was placed in the oven.
Jones's bond was set at $500,000.
"That was the only person who was there with the child at the time", Williams said. "This is one of the most awful things I've seen in doing law enforcement". The child's body has since been moved to the Mississippi Crime Lab for an autopsy.
Sheriff Kelvin Williams confirmed at a news conference that the toddler was found in an oven and had been burned, according to TV station WREG video of the news conference.
A woman in Greenville, about 20 miles (32 kilometres) from Shaw, pleaded guilty to killing her 3-year-old son in a heated oven in March 2011.
Neighbors told reporters that they rarely saw anybody leave or enter the home. "The hardest part ... is to see a child victim".
Robinson pleaded guilty to the murder and received a sentence of life in prison.
Washington County Coroner Methel Johnson said an autopsy found Robinson died from heat injuries sustained in the electric oven.
