Any NASCAR historians out there?

I was dabbling in a little bit of Redneck Haiku and came up with this one:

Leroy Yarbrough
Was the best goddamned driver
Ever to kill his mom

And then I got to thinking about it. Did Leroy Yarbrough really kill his mother, as I learned as a mere eight-ounce pop-top to my father’s Tall Boy, or was Dad just joshin’ me?

As a bit of background, Leroy Yarbrough (not to be confused with Cale Yarborough) was a very talented driver who ran about the same time as Richard Petty, Cale, and the Allison Boys in the mid-to-late sixties. Then he disappeared while the others shot to superstardom in the 70’s and 80’s. There isn’t a lot of information about Leroy on the Internet, unless I’m misspelling his name.

I don’t think this inquiry is solid enough to be a GQ, so I’m just asking this: anyone remember Leroy?

I remember LeRoy, but know nothing about him killing his mom. I’m not a NASCAR historin, I just was following it when the current guys’ dads, granddads, and (now) great granddads were driving.

NASCAR History:
