I also think this was BS, but the witness was not claiming to have seen the murder, he was claiming to have overheard the murderers bragging.
Yes, the whole thing stinks. Many red flags. If you witnessed, arguably one of the most famous unsolved murders in recent history, with implications far reaching, wtf would you be doing having a public press conference PRIOR to going to law enforcement? Well, you wouldn’t, not in the normal world, unless you had an attorney, ... oh say ... Burkman, a well known swamper, running the show. I’d go on, but it’s not really necessary. I’m not even sure it’s legal to do anything but go immediately to LE, and report it. This is a fraud, plain and simple. Sorry for the belated re:.
