According to an eyewitness, Bobby was traveling with his wife Alicia Etheridge and son Cassius, but became so intoxicated before boarding he almost didn’t make his flight.

“It was obvious in the terminal that he’d been drinking a lot. He was staggering and several of his family members had to hold him up in order to board the flight,” Brian Brown (no relation), who was taking the same flight, exclusively told RadarOnline.com.
