Deadly drag-racing setup questioned

One day after a drag-racing car plowed into a crowd at a charity event, witnesses questioned why the driver was allowed to speed down a multilane highway with no guardrails, lined on both sides by hundreds of spectators.

Two more people died, raising the death toll to six.

A Tennessee Highway Patrol spokesman said the victims were in their teens and early 20s. The accident injured at least 18 others, including a 5-year-old boy, who were taken to hospitals in Tennessee and Mississippi.

Authorities identified the driver as pro drag racer Troy Warren Critchley, an Australian who is now based in Wylie, Texas. He suffered minor injuries and was driven to a nearby hospital for treatment, authorities said. Police said he faced no criminal charges.
