The Los Angeles Times said the documents concern the theory held by Smalls' family, which has maintained the rapper was murdered back by a corrupt police officer.
The family, along with former LAPD detective Russell Poole, had alleged that corrupt LAPD detective, David A. Mack, had conspired with rap entrepreneur Marion "Suge" Knight to fatally shoot Smalls.
The newly found police records show how such a theory was developed by Poole and may help the family's claim when its wrongful-death lawsuit is back in court this summer, the Times said.
Police long ago dropped both Knight and Mack, now in prison on a separate robbery charge, as suspects and both have denied any involvement in the death of Smalls, who performed as the Notorious B.I.G.
