Found this:

On October 29, 1982, after finishing a gig in Beaumont, Texas, my band Vince Vance & the Valiants was driving in our personnel vehicle up Highway 287 to Dallas. At the same time, in those wee hours of the morning, a young man was driving to work, to his job as an assistant produce manager at a Brookshire Brothers Supermarket. He had been up all night planning his wedding. He fell asleep at the wheel, veered into our lane and went head on with us. Two lay dead at the accident scene: the grocery clerk and my lead guitarist, Richard Arthur Heath, who had been sitting shotgun. In Texas, that's the front passenger seat. The rest of us were all hospitalized for fractures, broken bones and much worse.
