The Wyoming family was driving to a doctor's appointment when a distraught teenager saw his chance in their headlights, authorities say. Matthew Denton throttled his SUV to 97 mph, steered into the opposite lanes, and kept his foot off the brake.
The head-on crash just after midnight Nov. 10 killed five people including 17-year-old Denton and four in a Dodge Caravan minivan: 41-year-old Corina Surrell-Norman; her ex-husband, Arvin Surrell; their 25-year-old son, Ethan Surrell; and his 20-year-old girlfriend, Melinda Escamilla.
Thursday's announcement by the Wyoming Highway Patrol that the fiery wreck was a murder-suicide came a day after burial for the four in a tribal cemetery.
