An all-too-familiar sight hangs from a guardrail on Jarrettsville Pike in Phoenix — a makeshift memorial of flowers marks where a teenage motorist lost his life.

Red, yellow and green carnations rest at the bottom of a windy dip in the road, where 17-year-old Dennis Woolford, of Phoenix, apparently crossed the double-yellow line while driving his 1997 BMW and crashed head-on into a 1996 Jeep Grand Cherokee driven by Gabrielle Payne, 17. Payne survived the crash. Woolford didn’t.
