Manhattan's district attorney announced Wednesday that he would ask a court to vacate the convictions of two of the three men convicted of murdering civil rights leader Malcom X in 1965. Here is a timeline of key dates related to the assassination and the prosecution of the men originally said to be his killers:
— March 9, 1964: Once a leading spokesman for Elijah Muhammad’s Nation of Islam, Malcolm X announces that he is breaking with Muhammad’s Black Muslim group and organizing his own.
— Feb. 14, 1965: A firebomb tossed through a window explodes in Malcom X's living room in Queens, hours before dawn. He flees the burning house with his wife and four children.
— Feb. 21, 1965: Three gunmen kill Malcom X as he begins a speech at the Audubon Ballroom in Manhattan. He is 39. Mujahid Abdul Halim, then known as Talmadge Hayer or Thomas Hagan, 23, is arrested at the scene after being shot in the leg by a bodyguard.
— Feb. 26, 1965: Muhammad Aziz, 26, then known as Norman 3X Butler, is arrested in the assassination.

— April 27, 2010: Halim is freed.
— April, 2011: Historian Manning Marable publishes “Malcolm X: A Life of Reinvention,” a biography that concludes that Aziz and Islam are innocent and brings new attention to claims that some of the actual killers were still at large. It wins a Pulitzer Prize.
— Feb. 7, 2020: Netflix begins streaming episodes of “Who Killed Malcolm X?” The six-party documentary examines the assassination and evidence that members of Halim's Nation of Islam mosque in Newark, N.J., were behind the killing. The Manhattan district attorney's office says it will consider reopening the investigation.
