The Notorious B.I.G.’s mother, Voletta Wallace, says her son’s death still hurts “every single day” 20 years after he was gunned down outside of a Los Angeles party on March 9, 1997.

Speaking with Daily Mail, Biggie’s mother shares her heartbreak as she reflects on the unsolved murder case of Christopher Wallace, who was killed at the age of 24.

“Any mother who has lost a child knows exactly the devastation I feel,” she shares. “It’s the worst pain in the world and one that I wouldn’t wish upon my worst enemy.

“He was so young, so talented and his life was taken far too soon. It’s unnecessary that Christopher lost his life at just 24. He was my baby, and I think about him every day.”

She also claims that she believes she knows who killed her son.

“I have a very good idea who murdered Christopher and I genuinely believe that the LAPD know exactly who did too,” she says. “They’ve done their investigation, but they just refuse to move forward. I don’t know why they haven’t arrested who was involved. It seems to me that it’s one giant conspiracy, and someone is definitely being protected somewhere down the line.”

Former detective Greg Kading, who is responsible for the book and film Murder Rap: Inside The Biggie & Tupac Murders, had previously spoken to Wallace about his findings into her son’s death. Kading claims that Puff Daddy hired a hitman to take out Tupac and that Suge Knight retaliated by hiring someone to kill Biggie.

Wallace says she has found solace in turning to God and staying involved in church, but that she will not have ultimate peace until there is justice for her son.

“There’s no closure for me until that murderer is behind bars and sentenced,” she says.

The cases of Tupac and Biggie will be analyzed in the television drama Unsolved coming to USA Network. The GMC Suburban that the New York legend was shot in is currently up for sale for $1.5 million.
