An Atlanta man has pleaded not guilty to charges in the boating collision death of music star Usher's 11-year-old stepson.
The Times of Gainesville reports that Jeffrey Simon Hubbard (pictured, right) entered the not guilty plea Tuesday to all charges, including first-degree homicide by vessel.
The boy, Kile Glover, was the son of Usher's ex-wife, Tameka Raymond.
Authorities say Kile and his father, Ryan Glover, were vacationing at Lake Lanier when Hubbard crashed a personal watercraft into the boy's raft July 6. Kile died at a hospital July 21.
The indictment also lists Jordan Shepp, who was tubing with Glover at the time of the accident. She was "seriously disfigured" by the collision, suffering injuries to her scalp and arm.
Hubbard, whose lawyer Jeff Talley entered the plea on his behalf, also pleaded not guilty to charges of reckless operation of a vessel, unlawful operation of a personal watercraft, boat traffic violation and serious injury by vessel.
If Hubbard is convicted he faces at least three years in prison.
