Update: Two weeks after his conviction on "homicide by vehicle," the man whose Jet Ski hit and killed Usher's stepson in 2012 has been sentenced to four years in prison.

2/20 Story: Nearly two years after Usher's stepson passed away, his accused killer has been convicted of homicide. Kile Glover—the 11-year-old son of Usher's ex-wife Tameka Foster—was hit by a Jet Ski in July 2012 and died less than two weeks later.

The convicted man, Jeffrey Hubbard, was operating a Jet Ski in Georgia's Lake Lanier on July 8, 2012, when his vehicle collided with an inner tube carrying Glover and a female friend. His companion lived, but Glover was pronounced brain dead and taken off life support days later.

According to USA Today, the court found Hubbard guilty of "homicide by vessel, serious injury by vessel, reckless operation of a vessel, unlawful operation of a personal watercraft and a boat traffic violation." 

Hubbard's attorneys attempted to convince the jury the entire incident was a tragedy, but not his fault.
