After a difficult upbringing as Trejo notes in his memoir, "Trejo: My Life of Crime, Redemption, and Hollywood," he spent 11 years in and out of California's most notorious prisons for crimes including selling drugs and armed robberies. 

In a 2021 interview on "CBS Mornings," Trejo said he vowed to change his life after a moment in 1968. 

"I made a promise, 'Lord if you let me die with dignity, I'll say your name every day and I'll do whatever you can for my fellow inmate.' And I said inmate because I never thought I was getting out of prison," he said. 

He went on attend Alcoholics Anonymous meetings, and after being released in 1969, he became a drug counselor. About 15 years later, he stopped by the "Runaway Train" set trying to help a struggling addict. Andrei Konchalovsky, the movie's director, took notice of Trejo's stare, and when he learned he had been a boxing champ in prison, he put him in the ring with Runaway Train star Eric Roberts. It launched Trejo's career and he now has some 400 on-screen appearances. 

"Everything good that has happened to me has happened as a direct result of helping someone else," Trejo told CBS Mornings.
