Have to admit, I was curious myself about where some big U.S. papers played this story, so I spent some time at newseum.org.
Indy Star had a 1A story (since Wheldon won Indy 500) and the Las Vegas RJ did, too, of course (since it was a local story). New York Post had it on the cover, but I suspect it was mainly because they could run a big photo of an explosion next to the words "ORGY SPREE" in 200-point type (for a story about Dominique Strauss-Kahn's exploits).
By and large, though, most big papers -- both east coast and west coast -- had nothing more than 1A teases: LA Times, Wall Street Journal, Washington Post, Chicago Tribune, Philly Inq, Boston Globe, Denver Post. UK papers (he's from England) didn't appear to have it out front, either, but that's probably more a factor of the time difference.
St. Petersburg Times had a full story on 1A, naturally (he lived in St. Petersburg). Surprisingly, the crosstown rival Tampa Tribune did not (1A tease).
My magazine interviewed him three years ago for an at-home profile. Nice guy. Sad news.
