On August 25, 2020, we checked the COVID-19 situation at the California Medical Facility at Vacaville where Ed Kemper has been incarcerated since 1973. It seems that the coronavirus has not been a threat, as only six cases were confirmed at the institution, five of which have been resolved since they were reported in late July – early August. No deaths are reported. The current forest fires and hot weather in California seem to be more serious threats at this point.
