A Hall County jury on Thursday also found Jeffrey Hubbard guilty of serious injury by vessel, reckless operation of a vessel, unlawful operation of a personal watercraft and a boat traffic violation. The summer 2012 crash on Lake Lanier northeast of Atlanta killed Kile Glover and left another teen severely injured.
Investigators have said the jet ski Hubbard was riding hit the children as they were being towed on an inner tube. Glover died of head injuries six days later.
Hubbard's attorneys argued that what happened was a tragic accident and wasn't linked to recklessness.
