First, let me say that the name commonality is just coincidence. But I agree with your finding it 'noteworthy'. PM me if you want other proof, and I'll provide it (DL photo, Skype, etc.), nbd.
Second, great memory. Thank you. Can you answer any of these questions:
1. Did it seem like there was one person making these videos with a handheld video camera or cell camera? Or was this like a dashboard camera?
2. So there was talking in one video (with the two drunk girls), was there talking in any of the other videos? Was he driving a taxi?
3. From what you say these were just some boring videos of random places with occasional loud noises thrown in. Was there anything obvious that connected the videos to the murders?
4. Did the Claremont Ghost comment on other videos? Did he reply to others' comments on his videos?
5. Any idea how the police connected the videos to the CSK?
6. Did the man have a Lebanese accent? Could you see anything about him (skin, hair, etc.)
7. As far as your own personal beliefs, are you convinced this guy was involved? Could he have just been an attention seeker?
If you know and can answer any of these questions, I'd love to hear it. Or anything else you remember.
