Thomas Hagan, the only person who admitted his role in the assassination of civil rights icon Malcolm X, was paroled April 27 after spending more than 40 years in prison, according to CNN.

Hagan, 69, took part in a work-release program that allowed him to live at home with relatives in Brooklyn, N.Y., five days a week while being imprisoned two days.

According to the report, Hagan pleaded his case for release and said he plans to become a substance abuse counselor. This was the 14th time Hagan had gone before the 14-body parole board.

However, Hagan was unlike others charged in the slain leader’s murder and was the only suspect to admit guilt.

“I have deep regrets about my participation in that,” he told the parole board on March 3, according to CNN. “I don’t think it should have ever happened.”

Hagan was sentenced to 20 years to life jail time after he was found guilty in 1966. Two other men were also imprisoned, but were released in the 1980s.
