Los Angeles Police Department detectives have issued an apology to the family of the Notorious B.I.G. for not warning them prior to the release of the rapper’s autopsy report.

The report was made public more than 15 years after Biggie died after a drive-by shooting.

According to USA Today, detectives intended to notify the Brooklyn emcee’s family, but the report was released prematurely “due to an administrative error.”

The LAPD released the following statement:

Our detectives personally spoke with the Wallace family (Friday) night, and apologized for not notifying them prior to the release… Obviously this has been a challenging case for us to solve. We hope that witnesses or other people with information will come forward and give us the clues we need to solve this case.

After the report’s release, the Wallace family’s attorney criticized the police for releasing the report, and not solving the murder.
