This is clearly bullshit.
At every turn, he attaches quantities to resources:
75 cheap laptops
8 of the women lived with him
2 people in the Nicaraguan Hezbollah camp
3 people in Mexico dealing with the Zetas
The only "evidence" supporting his story are his "so easy to fake my kids could it" screenshots and audio files.
I think the original assessment stands: This is a guy who has snorted waaaay too much MPDV, is seeing shadow men in bushes, and killed his neighbor in retaliation for his neighbor killing his dog.
He escaped the country via a combination of his charisma, money, and the ineptitude of the Belize law enforcement.
This is all just a retroactive attempt at explaining why the Belize government would want to frame him. Look, it's simple...why would Belize kill his neighbor to frame McAfee, when they could simply just kill McAfee instead?
Paranoid bullshit, and so obviously so.
