When did Hans Holzer investigate the house, and what was his findings?
Hans Holzer investigated the house on January 13, 1977. He brought with him Ethel Myers, a deep trance medium who sensed that the house was built on a sacred Indian burial ground. In addition, Hans claims photos taken during that investigation show evidence of paranormal activity, including a white cloud of “ectoplasm” which Hans says clearly looks like a man on a horse. Upon visiting the Amityville Historical Society, Holzer claims he was told the skeleton of an Indian Chief was unearthed on Ocean Ave. in the early part of the 20th century. Hans believes that Ronnie DeFeo was “under the power and the influence of the Indian” during the murders.
