ROCKY MOUNT, N.C. (WNCN) — A Rocky Mount mother and her boyfriend have been charged in the deaths of her baby son and toddler daughter Saturday morning, police said.

The incident was reported as an “assist EMS call” around 9:20 a.m. in the 900 block of Drew Street, according to a news release from Rocky Mount police.

EMS was called about two unresponsive children in a parked car, police said.

The two children were pronounced dead at the hospital, police said.

Saturday night, police said the suspicious deaths were classified as homicides.

Noel and Butler were released after they each received a $100,000 unsecured bond, police said Sunday.

Police said the case is still under investigation.

“Further charges may be pending, awaiting the reports from the North Carolina Medical Examiner’s office,” the news release said.

Noel and Butler are set to appear in court Monday at 9 a.m at the Edgecombe County Courthouse in Tarboro.
