MIDDLETOWN, Ohio (AP) – Police say officers responding to a report of a possible dead child at a southwest Ohio motel found a pair of young siblings with serious injuries and arrested their mother and two other adults.

Middletown police say they found a 5-year-old child with life-threatening injuries Wednesday night, and while investigating, they discovered the child’s 6-year-old brother seriously hurt and hidden under a blanket.

Police didn’t release details about the children’s injuries or how they were hurt. Both were taken to hospitals.

According to WLWT, police have arrested the mother of the two children, Theresa Hawkins-Stephens, 26, her friend Rachael Bostian, 29, and Bostian’s mother, Ramona Bostian, 56.

All three were staying in the motel room.

It wasn’t immediately clear whether they have attorneys. They’re scheduled for arraignment Friday.
