Langenfeld, Dan: - Dan Langenfeld was born in Racine, Wisconsin and has lived most of his life in Michigan's Upper Peninsula. He grew up under the influence of the occult and has spent the past twenty-five years studying the occult and demonology. Over the past few years he has interviewed more than 400 people with paranormal problems in their lives. The information from these interviews is the basis for this book. Dan is a veteran of the United States Marine Corp, honorably discharged in 1989. He has been actively involved with programs for kids over the years, including coaching little league for ten years, teaching Sunday school for teenagers as well as adults, while serving as Director for his local Awana program. Dan and his wife, Michelle, currently reside in Carney, Michigan where Dan owns and has been operating his own small business for fourteen years now. Please feel free to contact Dan at: swordofthespirit66@yahoo.com, or you can reach him on his Facebook page, Upper Michigan Paranormal Truth Seekers. He says, It doesn't take rocket science or an advanced degree in anything other than common sense to know that 'secret friends' who tell children to hurt themselves or others are no friends at all, but something sinister, evil, with diabolical designs on yet another human being.
