No, it is not a "fact" that he forged her signature. No one here has said that.
I find it a common misunderstanding what "fact" and "opinion" mean, to the point that I clearly state that something is my opinion, and then later someone says I was stating it as fact. When I say something is a fact (such as when JB lied about RG taking life insurance on GG) I have the evidence to back it up.
Fact: Something that can be proven by visible evidence.
Opinion: Something that may or may not be based on facts.
What is a fact is that GG took out travel insurance on RG, and named himself as beneficiary in the event of her death. There are documents that show this (discussed at length in this and earlier threads.)
Per numerous sources, the figure of that policy is 1.5 million dollars.
When the signatures are examined on the beneficiary forms signed by RG in April and July (the April one was for a cruise she cancelled) it is a fact that the signatures are distinctly different. That too was discussed at length in this thread.
My opinion is that one or both of these forms were forged. That remains to be seen. A clue that I am right is that Taco Stein said one of the charges they were considering is insurance fraud, but until we see what evidence they have, such as RG's actual signature and expert analysis, we don't know for sure.
Look at GG's alleged criminal history (not all of this is necessarily factual, but for the purpose of getting a glimpse into what he is possibly capable of) plus witness statements and you will see a lot of other "obvious" blunders in his choices for crime. Walking out with a shopping cart full of stuff at Target, stealing jewelry from Costco, stalking a woman in a jackalope mask, raping a woman on camera, forging a signature to a multi-million dollar contract, etc. This is stupid stuff. What makes you think he suddenly went non-stupid?
As for why no remains have been found, it might help if they actually looked for her. Trying to do it without cadaver dogs is a joke.
MOO.
