Hi bourne ~ I'd bet you a fiver that "that friend" is a doctor who is a neighbor of JS' in AZ, and also happened to have arrived in San Diego - Coronado the day before RZ met her violent suspicious death. IMO painting a picture that JS was devoted and madly in love with RZ would make it seem close to impossible to fathom that he could be directly or indirectly involved in her murder, at least in the public's eye. Mr. Machiavelli himself..
As to my thoughts on parallels between JonBenet and RZ case, I will get back to you on that ASAP. Am up to my ears in work at the moment...
Supposedly Jonah's close friend, Denise R, had been quoted telling reporters that proposal story. I just ran her name and she claimed to be a long time friend of Jonah's close friend for decades. From articles in papers, the published police reports, and statements in the Anne Rule book, it appears every single one of Jonah's friends were concerned about the misery and chaos Dina brought into Jonah's life. So even if the proposal seemed far fetched, the wishful thinking for Jonah's happiness was likely very real.
