It has been more than 25 years since the death of The Notorious B.I.G. and his unsolved murder case continues to spark ongoing theories.

Southside Crips member, Keefe D, and the uncle of the man who allegedly murdered Tupac Shakur has added possibly another key fact in the search for The Notorious B.I.G.’s killer. The Brooklyn-bred rapper’s murder was one of the nation’s most high-profile unsolved murders. And with a new theory added to the mix, Keefe D believes rapper, DJ Quik set Biggie up to be murdered.

During an interview with The Art Of Dialogue, Keefe D also shed’s light on former Death Row Rapper Jewell’s possible involvement and suspected he was the “central figure in the plot to murder Biggie.” Keefe D added to his theory and claims that “Quik and DJ Theo of Real 92.3 as potential suspects.”

“People be saying that she set him up and [stuff] like that,” Keefe says of Jewell. “That’s what the streets be saying, but I don’t think Jewell would do that. Me myself, I think Theo and them did ’em. Theo, the DJ dude, that’s who I think done him, in my true opinion. Him and Quik, that’s what I think.”

Although it’s not clear whether Quick and Theo were directly linked to the Juicy rapper’s death, Keefe D believes they played a pivotal role even though they weren’t the ones to pull the trigger.

“I just think the set-up went down in that type of way,” Keefe said. “But I don’t think homegirl did it ’cause Puff told me that they were there to sign with his label.”

Keefe D also claims that he warned Diddy about Quik’s heavy ‘blood’ association “outside of the Peterson Auto Museum prior to The Notorious B.I.G.’s murder.”

“He showed up with them dudes, them Blood dudes,” Keefe said. “My homies was out and was like, ‘Them ni**as are here.’ I went and relayed the messages to [Puffy] that DJ Quik and the dude Theo—he was a radio personality back then—was down there with them dudes. That’s where the sh*t went down.”

Keefe D believes that The Notorious B.I.G. would still be alive today if Diddy did not part ways with the Southside Crips the night the rapper was killed.

“Like I say, if we would’ve left with them. We had about seven or eight cars, we would’ve lined up with ’em, and no way in hell nobody would’ve gotten away. We were strapped up. Everybody had a strap so it would’ve been some sh*t I think he would still be here if they wouldn’t have called us off.”
