The character of Dr. Gonzo in the book and film Fear and Loathing in Las Vegas is based on a real person: a one-time military airman...turned Baptist missionary...turned legal aid attorney...turned Los Angeles County Sheriff's candidate...turned author...turned missing person. This is the story of the intriguing life and mysterious, unsolved disappearance of Oscar Zeta Acosta. We'll take a trip back to Los Angeles in the 1970s that features psychedelics, Chicano civil rights activism--and a lone, self-described brown buffalo wandering the halls of justice.
