The only thing I've been able to find is on the biographical page of his website
It doesn't seem to mention any double-blind tests. So, I don't know if any double-blind tests have been done specifically on the use of psychic abilities to find missing people. However, I do know that psychics have been tested using double-blind protocols, and so far none that I know of have ever demonstrated an ability to perform significantly above chance.
So even assuming Rodney is correct that the ability to find missing people cannot be adequately tested (although I see no reason why it couldn't be), I would settle for a psychic proving in a double-blind test that they have any psychic ability before being allowed to work with police to find missing people.
