Malikah Shabazz, the daughter of civil rights activist Malcolm X, was found dead inside her Brooklyn home Monday evening, according to two senior police officials.

The 56-year-old Shabazz was found unconscious and unresponsive inside her home on East 28th Street in Midwood just before 4:30 p.m., the police officials told NBC New York. She was later pronounced dead.

The city’s medical examiner responded to the scene and said the incident was not deemed suspicious. A cause of death has yet to be determined.

Shabazz, one of the twins and one of six siblings, was born after their father was killed.

Her death comes less than a week after two of Malcolm X’s convicted killers were exonerated following decades of doubt about who was responsible for the civil rights icon’s death.
