The incident report, obtained by MTV News from the Georgia Department of Natural Resources, did not name the injured children, but said Jeffrey S. Hubbard was operating the watercraft in Atlanta's Lake Lanier. Hubbard turns out to be a friend of the family.

Sgt. Mike Burgamy with the Georgia Department of Natural Resources told the Daily News, “One minute the jet ski was running around, the next he ran over the top of them. It happened that quickly,” he said. “It appears the watercraft did strike both juveniles, with the male taking the brunt of the force.”

Glover has reportedly been declared brain dead by doctors, but officials have declined to speak of his condition, citing privacy issues. The second victim, a 15-year-old girl, is said to have suffered a cut on the head and a broken arm.
