The foster parents of a 3-year-old disabled boy who died after being wrapped in a blanket and packing tape for two days were indicted Wednesday on murder and kidnapping charges.

Prosecutors have accused Liz and David Carroll Jr. of wrapping Marcus Fiesel in the blanket and tape and leaving him in a closet while they went to a family reunion in Kentucky in August.

The boy was dead when the Carrolls returned two days later, authorities said.

The couple initially were charged in neighboring Hamilton County, where they were accused of concocting an Aug. 15 report that the boy had gone missing from a public park. Hundreds of searchers helped look for the boy for four days.

Besides the new murder and kidnapping charges, the grand jury in Clermont County indicted the Carrolls on charges of involuntary manslaughter, kidnapping, felonious assault and endangering children. David Carroll also was charged with gross abuse of a corpse. The murder count carries 15 years to life in prison if convicted.

Both Carrolls are expected to be arraigned Thursday.
