Iron River, in Michigan’s Upper Peninsula, is known for its scenic lakes, hiking trails, exceptionally cold winters and dense forest. It’s sparsely populated, and many who do live there are blue collar workers. Laura Frizzo was the first female Police Chief in Upper Michigan and worked for the city of Iron River for almost 22 years. She knew what sorts of crimes to expect. And then came a woman named Terri O’Donnell. Towards the end of October, 2014, 50 year old Terri arrived at the police station and told authorities that her ex-partner, Chris Reagan, was missing.  What would unfold over the following months, and then years, is a story of extramarital affairs, drug abuse and serial murder. One woman would come to be known as the black widow - capable of crimes far worse than anyone could have imagined. This is part one of a two-part feature.   CREDITS Guest: Laura Frizzo Host: Jessie Stephens Producer: Lem Zakharia Audio producer: Ian Camilleri  Executive Producer: Zoe Ferguson LINKS The true story is dramatised in the new docu-series Dead North on Investigation Discovery - available to stream via Foxtel On Demand.
