We spoke with Sylvia Shults, author of "Fractured Spirits: Hauntings at the Peoria State Hospital" about her particular interest in that hospital, once known as the Illinois Asylum.
Her time as a paranormal investigator has given her many interesting stories involving the supernatural, which she expertly describes in her books, which include the above title and "Days Of The Dead: A Year of True Ghost Stories".
These, and all of her other works on the subject can be found on Amazon.com and by visiting her website at http://www.https://sylviashults.wordpress.com/
