A federal judge postponed a retrial Monday in a wrongful death lawsuit brought by the family of slain rapper Notorious B.I.G. against the city.

Judge Florence-Marie Cooper postponed the retrial to Jan. 16 to give the family’s attorneys more time to seek information from the defense.

The rapper, whose real name was Christopher Wallace, was shot and killed in 1997 after a party in Los Angeles. The murder has not been solved.

In the lawsuit, the rapper’s family claims that rogue police officers were involved in the killing.

Last summer, Cooper declared a mistrial after finding that a police detective intentionally hid statements by a jailhouse informant linking the killing to former officers David Mack and Rafael Perez.

The judge also ordered the city to pay $1.1 million in legal fees and other expenses to the rapper’s family.
