Malikah Shabazz, the daughter of slain civil rights leader Malcolm X, was found dead in her Brooklyn apartment Monday, the NYPD confirmed to CBS News. Shabazz was found by her daughter and at this point, her death is not considered suspicious, police say.

CBS New York reports that her daughter found her unconscious at about 5 p.m., according to police.

Shabazz, 56, was one of the twins born to Betty Shabazz after Malcolm X was killed, Bernice King tweeted late Monday. King is the youngest child of slain civil rights icon Martin Luther King Jr.

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.

The news comes just days after a New York Supreme Court judge exonerated two of the three men convicted of killing Malcom X in 1965. Judge Ellen Biben’s decision followed a two-year investigation by Manhattan’s district attorney that determined Muhammad A. Aziz, 83, and the late Khalil Islam were “wrongfully convicted”.

In the five decades since Malcolm X’s death, Shabazz and her siblings had questioned the official narrative of the assassination and the role government agencies played in it, according toThe New York Times.
