That's what Florida highway troopers want to know after searching since Monday for a truck driver and his tractor-trailer wanted in a fatal hit-and-run......... Mariah King, 19, and Vincent Mathews, 24, were killed Monday evening while changing a flat tire on the shoulder of the Florida Turnpike in St. Lucie County, the Florida Highway Patrol said in a news release.
