Amanda Renee Harrolle, 33, (shown here) was indicted by a Denton County grand jury last week. She remains free on $20,000 bail, which was set shortly after she was arrested at the scene.
The incident was reported about 6 p.m. Aug. 12. The swimmers were in about 5 feet of water when they were hit by the boat, which stopped, investigators reported.
Domingo Ramirez Jr. has the update.
