The Warren Township Historical Society will host its next general meeting at 7 p.m. Wednesday, Sept. 14, where members will hear from Tony Olszewski of the McHenry County Paranormal Research Group. Earlier this year, the group investigated the Mother Rudd Home for evidence of paranormal activity. They believe they have identified some unusual presences in and around the house. Olszewski, the group's founder and lead investigator, will share the findings. The meeting is at the Mother Rudd Home Museum, 4690 Old Grand Ave., Gurnee.Copyright © 2014 Paddock Publications, Inc.
