Class B First-hand BFRO #15895

Possible vocalization heard in Marion, Illinois

December 1977 about 2 a.m. Marion, Williamson County, Illinois 1 witness

Account

During a holiday visit in heavy snow, the witness was awakened around 2 a.m. by a very loud, prolonged scream from outside the bedroom window. The witness stayed frozen listening, then found other household members awake, and was told it was probably a cat under the house. The next morning new snow covered the area, and later checks found no sign of cats, leading the witness to note its similarity to recorded alleged vocalizations.
