Police said former NASCAR driver Kevin Grubb died from an apparent self-inflicted gunshot wound to the head in Richmond, Va. He was 31. Grubb was suspended from NASCAR indefinitely in 2006 because he refused to submit to a random drug test after a Busch Series race at Richmond International Raceway.
