Jeff Adkins, left, and Todd Bonner of Detroit Paranormal Expeditions will lead an investigation at the Iron County Historical Museum the evening of March 4. Founded in 2016, Detroit Paranormal Expeditions researches and investigates reportedly haunted locations to help explain the causes of the phenomena experienced there. DPX investigates places ranging from personal residences to larger, more well-known locations. With more than 25 years of collective paranormal investigation experience, the group has found that many reported paranormal experiences can be explained rationally and scientifically. Some instances, however, remain unexplained.
