Rodolfo Cadena (c. 1943-December 17, 1972) was a Mexican-American mob boss and legendary figure in the Mexican Mafia prison gang. "Chy" Cadena was a wayward youth and a member of the "Varrio Viejo" Gang from Bakersfield, California. He was incarcerated at Deuel Vocational Institution after he and a childhood friend from the same street gang, "Richard Ruiz" who would become one of the founding members of "La EME", stabbed a Bakersfield man to death outside of the "Salon Juarez" dancehall in 1958. At the time of his conviction, Rudy was only 15 years old. While incarcerated, he earned the respect and admiration of the members of the Mexican Mafia ("La Eme") which was still in its development stage.
