There are many cases on record where gifted psychics and mediums have worked closely with police officers to find missing people and solve crimes. But there are very good reasons why police do not make this public.

1) Police are drilled in scientific procedures and forensic science. Their culture is very skeptical and the police want to appear able to do their job properly without help.
2) If it became public that the police use psychics, they would have hundreds of well-meaning amateur psychics contacting them and wasting their time.
3) Even the best psychics and mediums are only 80% correct. The information comes to them in pieces. They have to interpret symbols and snatches of words. For the police to invest money on a search that does not produce evidence would be very damaging. And, in any event, evidence from a psychic cannot usually be used in court.
4) Some psychics have been threatened because their involvement with police was made public. If police find a gifted psychic, they would want to protect them so they can continue to use them.

At the same time, some of the best psychic mediums have an informal relationship with a particular police officer but do not advertise the fact. They never get paid, and often the work is very stressful. Read testimonies from police officers who say that psychics gave them helpful information.

MEDIUM JOHN EDWARD'S PARTNERSHIP WITH A SKEPTICAL FBI AGENT

In the summer of 1998, FBI agent Bob Hill reluctantly picked up the phone to call the famous psychic John Edward. Bob didn’t expect much from the call, but he was working on an unsolvable cold case and had nowhere else to turn. What Bob never imagined was that the call would lead to a shattering of all his preconceived notions, a huge break in the cold case, and an unlikely crime-solving partnership that spanned twenty-five years. That partnership is now the subject of their new book, Chasing Evil: Shocking Crimes, Supernatural Forces, and an FBI Agent’s Search for Hope and Justice.
