CHARLOTTE, N.C. -- Suspended Nationwide Series driver Kevin Grubb was found dead on Wednesday in a Richmond, Va., area hotel.
He was 31.
Henrico Co. Lt. Richard Cosby said Grubb was discovered at the Alpine Motel just outside of Richmond at 11:30 a.m.
In a news release sent out Thursday afternoon by Henrico police, the investigation and autopsy showed Grubb had died of an apparent self-inflicted gunshot wound to the head.
Police said there were no indications of any drug use found inside the room. A toxicology test was done, but could take up to six weeks before results are known.
Grubb was indefinitely suspended by NASCAR on Sept. 11, 2006 after his second violation of NASCAR's substance abuse policy.
Grubb, the younger brother of former NASCAR driver Wayne Grubb, began his Nationwide career in 1997 with four starts for Grubb Motorsports. He ran in 16 Nationwide events for his father's team in 1998 with a top finish of second at Dover.
Grubb drove for Brewco Motorsports from 1999 through 2001, collecting 18 top-10s. After several failed seasons with two other teams he was scheduled to drive for Team Reno Motorsports in 2004, but failed a substance abuse test in March and was suspended.
The suspension in 2006 came after Grubb refused to take a drug test following a second-lap crash at Richmond. Failure to take the tests is considered an automatic failed test.
The next day Grubb claimed that he declined the test because of a concussion suffered during the accident and offered to take a test at that time. He reportedly claimed no memory of the refusal due to the head injury.
Grubb was a native of Mechanicsville, Va., a suburb of Richmond.
