Psychic detectives use ESP and paranormal abilities to solve crimes in conjunction with law enforcement. Although there have been criticisms as to the validity and success rate of their work, organizations such as the FBI and CIA openly admit to using psychics on cases. Psychic Detectives will use post cognition, clairvoyance, dowsing, remote viewing, and even communicate with the deceased to gather information and clues. There are many ‘true crime’ examples where psychics are part of the team of investigators trying to crack cold cases, with varying success.
