A daughter of slain Black civil rights activist , Malikah Shabazz, died Monday, the New York Police Department told CNN.
Shabazz, 56, was found unconscious by her daughter at her home in Brooklyn, according to the NYPD.
Police said the death appears to be due to natural causes at this time.
Bernice King, a daughter of the late Martin Luther King Jr., offered her condolences.
"I'm deeply saddened by the death of #MalikahShabazz. My heart goes out to her family, the descendants of Dr. Betty Shabazz and Malcolm X. Dr. Shabazz was pregnant with Malikah and her twin sister, Malaak, when Brother Malcolm was assassinated. Be at peace, Malikah,"
Shabazz is the youngest of Malcolm X's six daughters.
CNN has reached out to the medical examiner's office and to the Shabazz family.
Malcolm X was one of the most powerful voices in the fight against racism before his shooting death in New York in 1965.
He remains a symbol of inspiration for Black men and others moved by his transformation from a street hustler to a historic figure the late African-American actor Ossie Davis eulogized as "our own black shining prince."
The assassination came after a public feud between Malcolm X and the Nation of Islam's founder, Elijah Muhammad. Malcolm X had accused Muhammad of infidelity and left the Nation in March of 1964.
Last Thursday, two men convicted of the assassination were exonerated during a court hearing.
New York County Supreme Court Administrative Judge Ellen Biben granted the motion to vacate the convictions of Muhammad A. Aziz and the late Khalil Islam.
