A daughter of slain black leader Malcolm X was indicted in Minneapolis today in an alleged plot to kill her father's old rival, Nation of Islam head Louis Farrakhan. Qubilah Shabazz, 34, who was four years old when she saw her father gunned down nearly 30 years ago, was charged with trying to hire a hit man to kill Farrakhan, whom her family has long suspected of having played a role in Malcolm's death. Shabazz, who was released on a $10,000 bond, turned herself in after a seven-month FBI investigation. If convicted, she could be sentenced to 90 years in prison and fined $2.25 million. TIME Minnesota reporter David Skarjune says the prosecution will claim Shabazz and one other person -- presumably the hit man -- were involved in the conspiracy. And that person, who prosecutors said was not a Nation of Islam insider, will be a mystery witness in the trial.
