Yes, I am well aware. I mentioned that in my reply. I included the two young men just in case Alcala was not the photographer, which I also mentioned.
I'm not sure how probable that is, since law enforcement has labeled these images as his, butI do think it is theoretically possible for an image to have been his in the sense he possessed it vs he was there and a participant in whatever happened. Since others have raised the possibility someone else may have taken this photo, I noticed some similarities to the subject and both of those young men and noted.
My personal opinion: this person is probably yet another one of the countless people either never reported missing, or reported missing and purged when they turned 18 or shortly after. They;re probably not someone we will find in NAMUS, etc. So frustrating! Can't hurt to keep trying though.
Hope this clarifies.
