In 2012 Nancy Streitmatter was found dead in an industrial building on Oak St in Quincy, IL. Her death was ruled a homicide. I submitted a FOIA request about the case about 2 months ago. 2 days later, a Quincy detective shows up at my house to discuss the case. He didn’t tell me much, as it is an ongoing investigation. He did say “if this was a murder, they hid it very well”. Coroner discovered evidence of head injury prior to death. My feeling is that she was killed before, killer relocated body to this building, and the building set on fire subsequently. A salvage lumber business was renting out this building at 219 Oak St. I want to find out what happened. Any help?
