Maria Sue, 5, was struck by a Toyota Land Cruiser when she was playing in the family's driveway in Williamson County just south of Nashville, said Laura McPherson, a spokeswoman for the Tennessee Highway Patrol.

It was confirmed that the driver is one of Chapman's teenage sons, but the police did not identify name and his age.

"Maria was rushed to Vanderbilt Children's Hospital in Nashville, transported by LifeFlight, but died of her injuries there." said a statement on Chapman's website.

No charges are expected, McPherson said, as apparently her brother did not see the girl,

"It looks like a tragic accident," she said.

Chapman and his wife have promoted international adoption and have three daughters from China, including Maria. They also have three biological children.

Maria was the youngest of the Chapman's six children.
