I am not buying that it was the security guard as they said last August,I do not care what the 'authorities ' say about DNA.You read the second chapter in this installment,and you will know why I don't believe the MSM narrative on the Perry murder...

Regardless of whether this individual was actually the source of the enigmatic photograph, the picture itself is key to the Perry case. Another bizarre and frightening clue in the Arlis Perry case came from the hand of Arlis Perry herself. Arlis' own words offered dramatic testimony of the evident pre-planning involved in her murder. On September 27, 1974—fifteen days before her death—Arlis wrote a letter to her close friend Jenny in Bismarck. Jenny and other Dakota friends of Arlis were not interviewed by the California police.

In the letter to Jenny, Arlis wrote: "I had to laugh about your call to Bruce Perry. Mrs. Perry [Bruce's mother] made the same mistake. She called them, too. But the strange part of it is that his name is not only Bruce Perry but it is Bruce D. Perry, and not only that but it is Bruce Duncan Perry and he attends Stanford University, and he just got married this summer. One thing, his wife's name is not Arlis. Anyway, next time you get the urge to call, the number is . . . This time I guarantee you'll get the right Bruce Perry."

A question: was it plausible to believe that there were two Bruce Duncan Perrys studying at the same school, at the same time—both of whom had just been married?

There were not—but someone had taken out a phone in that name. And since Arlis was able to recite all that information, she almost certainly talked to that man.

Apparently, with the influx of students arriving for the fall semester, Arlis and Bruce had a considerable wait until their phone was installed. When Jenny and Bruce's mother tried to reach them, they spoke to an information operator who gave them the listing of the other Bruce D. Perry at Stanford. It would have been a university area exchange number, since both Jenny and Mrs. Perry would have told the operator that Bruce and Arlis were living on campus. "I asked for Bruce D. Perry at Stanford," Jenny recalled.

Both then called the other Bruce and were told they had reached a wrong number. Of course, this information reached Arlis, as noted in her letter. Arlis apparently then took the natural step of calling the other Bruce to tell him where she was living and to give him her phone number (after the unit was installed) so that if he received another wayward call he could give the caller Arlis' correct number.

But now the other Bruce—the false Bruce—would also possess Arlis' phone number and, almost certainly, her address. If he'd anticipated any difficulty finding her, his problem—via the fraudulent telephone listing—would have been covered in advance. Through this method, his victim could eventually find him—just as Jenny and Mrs. Perry did.

What was it Berkowitz wrote about Arlis? "Hunted, stalked and slain. Followed to California."
