We can't get the pictures over and can't quote because it's a personal site. On the sons Facebook site there are pictures of him with Johanna and Bernardo. Most of them are send by friends/associates who knew Bernardo in the late 60's. There is no doubt that he was the father. There are very few pictures of Johanna. Although she is mentioned, the comments about her are scars IMO. I would think, people who knew her would have send pictures of her as a model, by now.
I agree with both of you. We should look into the events closer to her missing. The timeline we have seems to pause somewhere between '71 and the summer of '78. What kind of events happened in between and after '78? Did she study, (there is mentioning of the University of Arizona) or work, who took care of the son?
Agreed; but for those interested it is easy to find pictures of both the son today (and a few years ago), and the father (in the Laurel Canyon days) on non-personal sites and compare. Obviously this needs you to know the identity of the son, but he is relatively easy to trace through his own involvement in this search on various sites.
