Fifty-eight years to the very day Malcolm X was shot and killed inside the Audubon ballroom in Washington Heights, his family along with their attorney announced they plan to sue city, state and federal entities they say are connected to his assassination.

“This will be a landmark case whether they compensate the family or we go to verdict,” said civil rights attorney Ben Crump, representing the family at a news conference Tuesday.

“J. Edgar Hoover, the head of the FBI, said on June 5th 1964, ‘do something about Malcolm X,’ in less than a year he was assassinated.”

Standing with Malcom X’s daughters Tuesday, Crump said he will sue the state of New York, the NYPD, the FBI and the CIA for $100 million for allegedly concealing evidence tied to Malcolm X’s killing.

This comes two years after two men convicted of his assassination were exonerated. Crump says their exoneration can help substantiate evidence in this case.

“We think that the truth will finally come to light and this family will finally get the legal redress that was due to them so many decades ago, talking about justice delayed,” said Crump.

At an annual celebration inside the Shabazz Center, family, friends and notable political activist Angela Davis gathered to honor Malcolm’s X life.

Many there said the community has long believed that the government was involved in the civil rights leaders’ death.

“What it tells us is everything that the Shabazz family have been speaking about for many years since day 1 clearly is coming to fruition,” said Dr. Traci Alexander.

“They just scratched the surface in terms of the government’s complicity in this situation. That’s one of the things I’ve been working on over the years. The FBI, CIA, state department, other governments agencies, national security. All those individuals are complicit to some degree,” said Herb Boyd.

The lawsuit will be sent to the city’s comptroller’s office.

In a statement a spokesperson for Comptroller Brad Lander said, “The Comptroller’s office takes the review of each claim against the city seriously and investigates them thoroughly. This one will be no different.”
