Anyway, rumors have it that there was more to the message than "Dear Policeman: I am God".

More than just rumors.
According to the news department of the station that received the tip
(I saw Gordon Peterson, station news chief, asked about the case on TV)
the reporter was told what the message was
but was asked not to reveal anything more
than the 5 words above.

the reporter was told what the message was but was asked not to reveal anything more than the 5 words above. ["Dear Policeman: I am God"]

So why were these 5 words revealed, along with the existence of the Tarot card itself?
