The story about how he met her was bullshit. Well, the gun bit was.
I noticed she laughed a couple of times when asked about his disappearance. She said his hand wouldn't fit in the meat grinder and laughed. Perhaps just a small thing but this type of reaction is very suspect.
She's a hypocrite. She was dealing in wildlife in the beginning.
Also when she relived her first cat purchase she said they flew to an auction and saved a bobcat from a taxidermist. That's not what taxidermist do, they do not pay top dollar for animals to kill and stuff them. But of course it makes her come across as a hero.
Working out where the tiger dude was doing shows and speaking to the people who ran the malls was super vindictive considering she was a "reformed exploiter"
100% she did it.
