Steven Novella writes about a popular new Californian "medium" -Grief vampires are self-proclaimed psychics or mediums who prey upon the loved ones of those who have recently died. They exploit the grieving for their own monetary gain.
(From his own website.)Tyler Henry (born January 13, 1996) is a teen clairvoyant medium oringally (sic) from central California. Born with a unique gift, Tyler has helped countless people acquire closure, comfort, and proof that consciousness transcends physical death. Working as an evidential-based medium, his ability to provide specific, detail-oriented specifics has allowed him to share what he sees with medical professionals and missing person cases.
