Cathriona had indeed gotten involved with Scientology, no doubt during or just prior to/after her work on "The Online Gamer", where she worked alongside many other Scientologists(apparently the cast and crew was made up of a lot of them), including Mark Burton, who she would later marry in an attempt to secure her citizenship - it has been said that either Cathriona or her mother, Brigid Sweetman, paid Burton up to $30,000 to marry Cathriona - after which they promptly resumed their own individual lives away from each other.

The relationship became toxic when Cathriona forged her medical records in an attempt to claim that Jim Carrey had given her herpes and/or other STDs - it seems very apparent that even this was something that Scientologists would have put her up to.

I wonder if scientology was behind the civil suit against carrey in order to pressure him into joining the fold due to possible evidence (the drugs she od on).

Not a doubt in my mind that Scientologists(including Mark Burton) and Michael Avenatti knowingly and fraudulently manufactured the circumstances and "wrongful death" claims filed against Jim - incidentally enough, there was a 4th pill bottle found with Cathriona's body which was not prescribed to Cathriona or the name suspected to be an alias of Jim; there was something else in her 'suicide' concoction, which she should not have had any access to - rarely mentioned anywhere except in a single article.

I've every reason to think that any "possible evidence" against Jim was fraudulently manufactured and/or taken out of context so as to continue with Cathriona's initial attempts to extort Jim - the question remains, was Cathriona trying to extort Jim of her own accord, or, were Scientologists threatening to expose her to I.C.E if she did not succeed in extorting a substantial amount of money from Jim? I believe it was the latter.

Or maybe she realized that scientology was using her as sex bait, and she threatened to go public, so they killed her to cover it up and made it look like a suicide, which they may or may not have done dozens upon dozens of times.

It's quite probable that she did realize this at some point and that she was willing to go public after reconnecting with Jim - indeed, Scientologists may have seen her reconnecting with him as a sign of weakness - that there was a growing risk of her telling Jim everything about her involvement with Scientology. Scientologists have indeed gone to very extreme lengths in similar campaigns of subterfuge and character assassination; see: Operation Snow White/Operation Freakout, discussed in Root of Corruption - Part 14: Wizards & Warlocks.

I read the ones you linked (well, mostly, some of it was hard, for me, to read). Nice work though! Keep it up! I appreciate your obvious hard work and dedication!

My apologies for the difficult reading, I've been trying to improve on formatting and providing summaries as I go along.
