As Def Sounds previously reported, the LAPD released the autopsy reports of the late great emcee The Notorious B.I.G.’s unsolved murder over 15 years after his untimely death this past Friday. Now, a spokesperson for the LAPD has issued an apology due to the fact that the report was released before the Wallace family had been notified, due to an “administrative error.”

As reported by the Detroit Free Press, detectives planned to inform Biggie’s family, but the report was released in advance “due to an administrative error.”

Capt. Billy Hayes, who heads LAPD’s Robbery-Homicide Division, which is investigating the murder, released a 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.

The apology comes after the attorney for the rapper’s family complained Friday that he was not given any advanced notice that the report would be released and criticized police for not closing one of Los Angeles’ highest-profile unsolved murders.
