*The family of Malcolm X has called for the investigation into his death to be reopened.

The move follows the release of a letter written by deceased NYPD officer Raymond Wood, alleging that the police and FBI were responsible for Malcolm’s murder in 1965.  Malcolm X killed at New York’s Audubon Ballroom while preparing to deliver a speech.

Under the direction of my handlers, I was told to encourage leaders and members of the civil rights groups to commit felonious acts,” Wood wrote in the letter. According to the report, he asked that the letter be released after his death out of fear of retaliation for breaking his silence.

“Several months ago, the Manhattan district attorney initiated a review of the investigation and prosecution that resulted in two convictions for the murder of Malcolm X,” the NYPD said in a statement, per BBC. “The NYPD has provided all available records relevant to that case to the district attorney. The department remains committed to assist with that review in any way.”

The three Nation of Islam members who were arrested in connection with X’s death were sentenced to life in prison. Talmadge X Hayer confessed to the murder and admitted in an affidavit that he considered with four others, according to the report.

“Any evidence that provides greater insight into the truth behind that terrible tragedy should be thoroughly investigated,” Ilyasah Shabazz, one of Malcolm X’s daughters, said.
