Vagos, Mongols, and Outlaws: My Infiltration of America’s Deadliest Biker Gangs - Charles Falco,

Vagos, Mongols, and Outlaws: My Infiltration of America’s Deadliest Biker Gangs is a gripping true-crime memoir by Charles Falco, written with Kerrie Droban. The book recounts Falco’s harrowing undercover work infiltrating three of the most dangerous outlaw motorcycle clubs (OMCs) in the United States: the Vagos, Mongols, and Outlaws.

A former meth dealer turned confidential informant, Falco risked his life living as a full-patch member within these violent gangs. Over several years, he gathered intelligence for the ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives), leading to major arrests and convictions.

The book gives an insider’s look at the culture of OMCs—highlighting their violence, drug trafficking, internal politics, and strict codes of loyalty. Falco’s story exposes both the brutality of gang life and the psychological toll of living a double life.

Raw, fast-paced, and brutally honest, Vagos, Mongols, and Outlaws became the basis for the TV series Gangland Undercover, where Falco’s undercover exploits were dramatized for a broader audience.
