A psychic detective is a person who investigates crimes by using purported paranormal psychic abilities. Examples have included postcognition (the paranormal perception of the past), psychometry (information psychically gained from objects), telepathy, dowsing, clairvoyance, and remote viewing. In murder cases, psychic detectives may purport to be in communication with the spirits of the murder victims.
Although there are documented cases where individuals claiming psychic abilities have assisted police in solving crimes, there is considerable skepticism in regard to the general use of psychics under these circumstances.
Many prominent police cases, often involving missing persons, have received the attention of alleged psychics. Following the disappearance of Elizabeth Smart on 5 June 2002, the police received as many 9,000 tips from self-proclaimed psychics (and others crediting visions and dreams as their source). Responding to these tips took "many police hours", according to Salt Lake City Police Chief Lieutenant Chris Burbank. Yet, Elizabeth Smart's father, Ed Smart, concluded that: "the family didn't get any valuable information from psychics." Smart was located by observant witnesses who recognized her abductor from a police photograph. No psychic was ever credited with finding Elizabeth Smart.
In the case of the Long Island serial killer, the psychic said the body would be found in a shallow grave, near water and a sign with a G in it would be nearby. Despite the vagueness of this claim (the body was not in a shallow grave, water is everywhere in Long Island, and no sign with a G was nearby) the New York Post stated that the "Psychic Nailed it!" "More surprising than the psychic's failure is the fact that this information was described as an amazing success on over 70,000 websites without anyone realizing that she was completely wrong."
When Washington, D.C. intern Chandra Levy went missing on 1 May 2001, psychics from around the world provided tips suggesting that her body would be found in places such as the basement of a Smithsonian storage building, in the Potomac River, and buried in the Nevada desert among many other possible locations. Each tip led nowhere. A little more than a year after her disappearance, Levy's body was accidentally discovered by a man walking his dog in a remote section of Rock Creek Park.
