Two excellent feature stories I've seen recently were from Justin Heckert and Vanessa Veselka respectively.
Published in the November issue of GQ was "The Truck Stop Killer" by Veselka, an account of her trying to find out if convicted serial killer Robert Ben Rhoades is the same person who picked her up as a teenage runaway hitchhiker in 1985. Pretty chilling piece that brings to mind "The Vanishing" by Bob Friel for Outside earlier this year.
As the latest New York Times Magazine cover story, Heckert provided "The Hazards of Growing Up Painlessly" on Georgia middle schooler Ashlyn Blocker. It's an absolutely riveting piece on Blocker as part of the rare subset of people who don't feel pain and what this means for their lives. Heckert a few months ago wrote "How to Build an American Car" for Esquire and this story on Blocker is another really solid piece of writing.
