A Netflix documentary series on the assassination of Malcolm X has helped to reignite the investigation into the assassination of civil rights activist Malcolm X.

The Manhattan district attorney's office said Monday that it would review the case after new information came to light and that they are working in unison with the Innocence Project, a non-profit that works to exonerate the wrongly convicted.

"District Attorney Vance has met with representatives from the Innocence Project and associated counsel regarding this matter," Manhattan DA spokesman Danny Frost said in a statement. "He has determined that the district attorney's office will begin a preliminary review of the matter, which will inform the office regarding what further investigative steps may be undertaken."

In the docuseries, historian Abdur-Rahman Muhammad investigates possible leads into the murder, speaking with members of the Nation of Islam, a religious organization Malcolm X belonged to until he was excommunicated.

Malcolm X was gunned down on stage at the Audubon Ballroom in New York on February 21, 1965. Following his death, three men were convicted in 1966. Mujahid Abdul Halim (known as Talmadge Hayer and Thomas Hagan), Muhammad Abdul Aziz (known as Norman 3X Butler), and Khalil Islam (known as Thomas 15X Johnson) were sentenced to life in prison. The latter two have always maintained their innocence.

"Given the historical importance of this case and the fact that our client is 81 years old, we are especially encouraged that Mr. Vance has assigned two highly respected prosecutors, Peter Casolaro and Charles King, to work on this re-investigation," Innocence Project co-founder and special counsel Barry Scheck said in a statement.
