About this listen

 Karl Sup is a seasoned software consultant, architect, developer, and analyst with a profound dedication to cryptozoology and paranormal research. An avid Bigfoot investigator, Karl has documented 13 sightings across Arizona, Maryland, Wisconsin, and Illinois, among other states, conducting extensive fieldwork in diverse regions, including Long Island, New York. With decades of audio analysis expertise, he has collaborated with M.K. Davis to enhance VHS tape recordings, uncovering evidence of infrasound potentially linked to Bigfoot communication. Karl maintains significant archival collections from researchers like Bobbie Short and Mike & Sandy Sells, preserving valuable cryptozoological data.

His investigations extend to other cryptids, notably the Piasa, a legendary winged creature from Illinois folklore. In 2013, Karl validated witness accounts of a large, leathery-faced entity near Grafton, Illinois, and recorded an associated screech. His paranormal sensitivity, sparked by an out-of-body experience at age 5, has led to numerous encounters with spirits and unexplained phenomena, including recent experiences on the Queen Mary. Karl’s UFO sightings include the 1997 Phoenix Lights, a 1975 triangular craft in Tempe, Arizona, and red orbs in Mesa in 2012. He also engaged with Travis Walton about his 1975 abduction.

Karl’s research is documented on http://www.ghosthuntingtheories.com featuring detailed Bigfoot reports, a psychometry reading of a Sasquatch-handled deer skull, and 11 Long Island Bigfoot accounts. His work, blending rigorous analysis with speculative methods, bridges cryptozoology, paranormal investigation, and UFOlogy, making him a prominent figure in the study of the unexplained.
