Firefighters Jim Carino, left, and Brian Schonborn inspect a Florida Rock cement mixer Thursday morning after it collided overnight with a waste disposal truck, background, on westbound State Route 580 just east of McMullen-Booth Road in Clearwater. The cement truck's driver, Charles "Ron" Sheppard, 52, of New Port Richey died in the accident. His truck had plowed through a guardrail and into a drainage ditch where it burst into flames. Clearwater Officer Scott Dawson said he sprayed the truck with a fire extinguisher as the flames spread, hoping he could save Sheppard. But police said Sheppard had been killed on impact, before the fire started.
