Lawyers representing California prisoners are asking a Federal judge to transfer thousands of inmates from what they describe as “toxic prisons” in the central valley. They made their case in a Federal court in San Francisco, following dozens of deaths and hundreds of hospitalizations at 2 prisons. The deaths and sicknesses are caused by a deadly fungal disease that can cause chest pains, fever, blindness, and even death. The illness has no known cure. Christopher Martinez reports from San Francisco.
