Murder, mayhem, and mail, fans of true crime will not want to miss the Grayslake Heritage Center & Musuem’s series, Mail-icious Crimes. There have been two programs over the last two months which have detailed local and regional history of how people used the mail to commit everything from local scandals to high profile heists. Each month, a different presenter has come and given a presentation on one of the crimes covered in this series. It’s now time for the third, and final program in the series - focused on a female serial killer.

La Porte, Indiana County Historian Bruce Johnson will be showing his documentary The Gunness Mystery and open a Q&A about the most prolific female serial killer in the United States.
