Cause Of Arizona Movie Set Fire Remains Under Investigation

TUCSON, Ariz. (AP) -- Investigators were still trying to determine Monday what caused a fire on the set of a Stephen King television miniseries.

The blaze at Tucson Convention Center on Friday injured five people and forced a concert evacuation.

Those who sustained burns were released by Sunday from St. Mary's Hospital, spokeswoman Jan Howard said.

Filming at Tucson Convention Center was not expected to resume until authorities determine whether special-effects dust released by the crew in ABC's filming of ``Desperation'' helped spark the fire.

Damage estimates were not available, but the cost was expected to be substantial, said Randy Ogden, a Tucson Fire Department spokesman.

Losses included cameras, props, computers and sound equipment, Ogden said.
