Blue Line Paranormal LLC is a Missouri-based paranormal investigation and research company founded in 2019 by Gage Mansfield. We conduct professional, respectful, and confidential investigations of private residences, businesses, historic locations, and reported unexplained activity.

Our approach combines investigative experience, careful documentation, audio and visual evidence collection, environmental monitoring, witness interviews, and objective evidence review. We do not exaggerate evidence or guarantee paranormal conclusions, and every case is handled with discretion, integrity, and respect for the people and places involved.
