Karen Pipkin Guerrero

Where did this idea come from? A journalist who reportedly had a special relationship with the FBI told a congressional attorney that she had transcripts of what appeared to be phone taps and bugs of Karen's telephone calls, though she never produced those documents.

If I can bother you for five minutes... Joe had found a source who, in 1970, had worked as a secretary for the Oklahoma City Police Department's Intelligence Unit. She'd left by the time Karen died and were not naming her because she told Joe she did not want her name attached to his investigation. She'd agreed to talk to Joe. But she was reluctant.
