Expert witness testifies in Libby trial.

The AP (3/11) reports that Dr. Aubrey Miller, "a medical expert testifying Tuesday in the W.R. Grace trial described his disbelief when, arriving in Libby 10 years ago, he found that people who had never worked at Grace's vermiculite mine were dying from asbestos-related disease." He said, "To see an individual who had died of asbestos-related disease who was not a worker was unheard of." He added, "I had never seen a case or heard of a case like that." The doctor "testified about a range of product tests that Grace officials used to assess the hazards of Libby vermiculite." He said, "Among its findings, Grace learned that the vermiculite had a high tendency to release asbestos fibers into the air."
