The county clerk says there is no record of Stern ever taking her oath which is a requirement of the position. Corinne Stern has held the position of medical examiner since early 2007. So the question that's arising now is ... Could her findings and conclusions in all previous cases be thrown out? "I'm sure that when she came in as a medical examiner, she should know by the state what requirements she has." When Webb county attorney Anna Laura Cavazos first heard the news last week that medical examiner Corinne Stern had not taken her state oath of office, she immediately started looking into the matter. "As of late friday afternoon, we checked with county clerk she was not able to find an oath of office." "We checked our bonds and we checked our oath, but i don't have anything on file as of now.” That brings up many questions including why she hasn't yet taken her oath... especially since she has been the medical examiner since 2007. County attorney Cavazos says she recently received a call from an attorney working on a local case... questioning whether or not stern had taken her oath. "Until such time as she has taken the oath with appointment as medical examiner then everything she did prior to that is void." She goes into the consequences further and explains just how it could effect all the cases stern has worked on. "It doesn't change the result, it only changes her authority to give the conclusions that she did as result as examiner." Although the county is currently investigating this issue, Cavazos is looking into a similar case dealing with a judge who never took his oath. "We did receive a citation of a case where that happened to a visiting judge, but a visiting judge is not a medical examiner so we are going to research and see how applicable it is." According to constitutional law, the county judge is required to take the necessary actions to make sure Stern is not working as the medical examiner without taking her oath. We tried to contact Stern, but never got a response.
