When the interviewer asked about Martin’s girlfriend, who said that he told her that he was being followed, Robert Zimmerman said he didn’t believe her.He replied: “I don't believe she was on the phone with him, and I find it very strange with the publicity involved with this that all of the sudden, after three weeks, someone would remember that they were on the phone. I believe the FBI and others investigating this will find that that did not happen.”
Martin's cell phone records will show if he was on the phone at this time, and what number he was connected to. Cell records of both parties have almost certainly been subpoenaed if the investigators are at all serious.
