While Tyrell and Shawn have an unexplained encounter near the ranch, Ventura seeks answers from Bigelow himself.
Season 2, Episode 1: Ventura investigates the secretive Plum Island Animal Disease Center located off the coast of Long Island, New York, which has been suspected as being a bio-weapons research center responsible for the release of Lyme disease and other deadly viruses.

Season 2, Episode 6: Ventura looks into the prospects of "Blue Gold" and why corporations and the super-rich are buying up water rights around the world in what could be a plan in controlling nations and their masses.

Season 1, Episode 6: In this episode, Ventura has uncovered a CIA conspiracy to create real-life Manchurian Candidates, brainwashed assassins who kill under orders but without any conscious intent.
This is an interesting case, because we know for a fact that the CIA at least attempted to do this in the 1970s as part of project MK-ULTRA. It's also true that many people with psychiatric issues can perform complex actions (like committing murder) while in a fugue or dissociative state. And furthermore, the act of committing murder could certainly create traumatic amnesia, such that the killer truly does not remember having killed someone.
