Jeffrey Hubbard has been sentenced to four years in prison in the sea scooter crash case that killed Usher’s 11-year-old stepson Kile Glover.

The incident in July 2012 on Lake Lanier near Atlanta killed Kile Glover and left another teenager injured.

A jury found Jeffrey Hubbard “guilty of homicide by vessel” last month.

Kile Glover had been raised by Usher since the age of four

In addition, Jeffrey Hubbard was found guilty of several other charges including serious injury by vessel and reckless operation of a vessel.

Investigators said the sea scooter Jeffrey Hubbard was riding hit the children as they were being towed on an inner tube.

Jeffrey Hubbard’s defense lawyers said he tried to avoid the children and that what happened was a tragic accident.

Since the incident, a bill has been introduced in America which lowers the blood-alcohol limit for boat drivers to match the car driving limit.

The bill also requires a boat safety education course for those operating motorized vessels bought after January 1998.

Kile Glover was the son of Tameka Foster Raymond and Atlanta television executive Ryan Glover, and had reportedly been raised by Usher since the age of four.
