Usher’s stepson, Kyle Glover, has been declared brain dead after a Jet Ski accident left him in critical condition.

Glover, 11, has had no brain activity since being admitted to the hospital, and is currently on life support. He sustained an injury to the head after being hit by a Jet Ski while in Lake Lanier, Saturday (July 7). The youngster was riding in an inner tube leading up to the accident, and was transported to a local hospital, where his mother, Tameka Foster Raymond, flew to be with him.

A representative for the Department of Natural Resources in Atlanta, confirmed that they are investigating the incident, to determine the speed of the water ski leading up to the impact. Depending on their findings, the DNR will give a recommendation to the district attorney, who will decide if criminal charges should be filed.

Usher and his ex-wife have been engaged in a very public custody battle, but the former couple put their difference aside in the wake of the accident. The 32-year-old chartered a plane for Foster Raymond, so that she could fly in from out-of-town to be with her son.
