A mother has been charged with felony child abuse and child cruelty after she allegedly forced two of her children to take turns riding in the trunk of a car on an eight-hour drive from Alabama to Virginia.

Cheryl Ann Schoonmaker, 38, forced the two girls, ages 8 and 10, to take turns in the trunk July 1 because there wasn't enough room in the car, according to Curtis Schoonmaker, her ex-husband.

The woman was driving five children, including an infant, to her ex-husband's home outside Washington, D.C. None of the children was injured during the trip. The girls told their father what happened the next day and he called police.

"They asked to be let out. ... It was a hot day," Curtis Schoonmaker said.

Efforts to reach Cheryl Schoonmaker were unsuccessful Monday.

Three of the five girls in the car were the Schoonmakers' children. One of the other children was a family friend and the infant was Cheryl Schoonmaker's.

Cheryl Schoonmaker is scheduled for arraignment July 22. The charges each carry a maximum of five years in prison.
