[3] The youngest of four siblings, Morgan was born on April 10, 1929, in San Pedro, California to Croatian immigrants Clara (née Radišić from Imotski) and Grgo Međugorac[citation needed], a truck driver who was an ethnic Croat from Ljubuski.
[3] In 1961, Morgan led eleven inmates in a jailbreak from Los Angeles County Jail through a pipe shaft and using hacksaw blades he hid in his prosthetic leg.
His connections with cocaine and heroin suppliers in Mexico helped pave the foundation for the Mexican Mafia's narcotics distribution throughout California.
Morgan was able to persuade the Aryan Brotherhood to forge a loose alliance with La eMe, due to having the Black Guerrilla Family as a mutual rival.
It was thought that Morgan wanted to set deals with white and black gangs to ensure La eMe would come out the dominant force with little resistance.
[citation needed] Allegedly, Morgan established diplomatic relations with the Los Angeles crime family through Michael Rizzitello, whom he and Rodolfo Cadena met during the nine-year sentence of the reputed mobster in Chino for a string of armed robberies during the 1970s.
[citation needed] On October 27, 1993, Morgan was diagnosed with inoperable liver cancer[6] while serving a life sentence at California State Prison, Corcoran.
