Speaking exclusively to DailyMail.com, Voletta Wallace, 64, admits she hurts 'every single day' knowing that she will never see her son again and that his killer is still at large.

And in a shocking claim, the matriarch of hip hop reveals that she and LAPD detectives investigating the murder DO know who is responsible for her son’s death but a 'conspiracy' prevents the case from ever being solved.

Biggie, whose real name was Christopher Wallace, was gunned down in cold blood on March 9, 1997 in a drive-by shooting in Los Angeles, aged just 24.

The ‘Juicy’ singer had earlier delivered his final performance at the Soul Train Awards before he was killed after leaving an after-party at the Petersen Automotive Museum in a two-vehicle convoy.

Trailed by fellow artist P. Diddy, who opted to travel in a separate car, his friend could only watch as the Brooklyn-born star was hit by four bullets from a driver in a Chevrolet Impala that pulled alongside his GMC Suburban SUV.

Speaking from her home in Stroudsburg, Pennsylvania, Voletta choked back tears as she recalled the shooting.

She said: ‘It hurts me every single day to know what happened to Christopher and that I won’t see him ever again.

‘And it’s not just me that is devastated, his sister T’yanna hurts every day because of his loss. As a family, we’ve collectedly grieved and it doesn’t ever get any better for us.

‘Any mother who has lost a child knows exactly the devastation I feel, 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.

‘When it comes to the anniversary of the passing of his death, I don’t really like to talk about it. I know there will be a few tributes in honor of Christopher, and that’s great he’s still remembered, but it’s very tough for me and my family.’

Many in the aftermath of Biggie's death claim the bullets were actually meant for P. Diddy (pictured), whose real name is Sean Combs, as a revenge killing six months after Biggie’s rap rival Tupac Shakur was also gunned down

Voletta, who is a devout Christian, admits she has turned to God for answers since the murder.

However, as comforting as the church is, it can never replace her son.

‘I get by, using religion to ease my pain. But that’s not easy. It helps a little, but it’s a far cry from bringing Christopher back to life,' she said.

‘I have had lots of support from friends at church, and I’m thankful for that over the years. People have been very nice to me, and that’s also because Christopher was such a glowing figure in their lives too.’

They claim Diddy is somehow linked to Shakur’s (pictured) murder in Las Vegas on September 7, 1996, a theory often rumored in hip hop circles

Voletta blames the LAPD for not solving the crime and claims detectives know exactly who was responsible.

‘I have a very good idea who murdered Christopher and I genuinely believe that the LAPD know exactly who did too,’ she said.

‘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.’

The longer the case goes unsolved Voletta, who is executor of Biggie's estate, knows it’s unlikely she will ever be able to put her son’s senseless killing behind her.

‘There’s no closure for me until that murderer is behind bars and sentenced,' she said.

‘That may give me some closure to grab onto, but it sure won’t ever bring my son back.'

Born on May 21, 1972, Biggie was raised in Brooklyn by single-mom Voletta, a Jamaican immigrant, who worked as a pre-school teacher.

It was a tough start to life and Biggie was selling crack on street corners by age 12 landing him with a long rap sheet and a stint in jail aged 17.

But in the late 1980s the troubled teen, who liked to rap as a sideline to dealing drugs, got his big break.

At 6ft 3ins and nearly 400lbs, he used the fitting stage name Biggie Smalls after Calvin Lockhart’s gangster character in the 1975 movie Let’s Do It Again.

One of his mixtapes was sent to an editor at hip-hop magazine The Source and Biggie was soon signed by Sean 'Puffy' Combs, then working for Uptown Records.

‘That soon escalated, and it is known in the circles that Suge (Knight) wanted to get revenge for losing his prized asset. He held Puff responsible and wanted to go after him,' the source said. Pictured, the black car in which Tupac was fatally shot

In September 1994 Biggie released his debut album, 'Ready to Die.' under Combs' newly formed Bad Boy Records.

Backed with hits like 'Juicy' and 'Big Poppa,' the record went platinum selling four million copies and the young hip-hop artist became a full-fledged star.

The album earned several awards including Billboard’s Rap Artist of the Year and Rap Single of the Year.

By then he had dropped his original name in place of The Notorious B.I.G. after Lockhart sued him over 'Biggie Smalls'.

The rapper's career went from strength to strength and he backed several other artists even working with Michael Jackson, on his 1995 album, 'HIStory.'

By the close of 1995, Biggie was one of hip hop's best-selling and most sought after performers.

He was married to R&B singer Faith Evans and they had a son, Christopher 'CJ' Wallace Jr., in 1996.

Biggie already had a three-year-old daughter, T’yanna, with another woman.

Theories around the shooting - now a part of hip hop lore - have reemerged in one form or another over the years as journalists and fans attempted to tackle the case.

But a source who was with Biggie the night he died is convinced the bullets were meant for P. Diddy, not him.

The source says he believes the bullets were meant for Diddy, aka Sean Combs, as a revenge killing six months after Biggie’s rap rival Tupac Shakur was also gunned down.

The claim that Diddy is somehow linked to Shakur’s murder in Las Vegas on September 7, 1996 has long been rumored in hip hop circles.

Earlier this week it emerged that the car in which Biggie was murdered in is now being sold by memorabilia dealer, Moments in Time for a staggering $1.5 million.

It was originally picked up by a woman in an auction in 1997, who had no idea how famous the vehicle was, according to TMZ.

Apparently, the passenger door was replaced after police officers removed it during their investigation.

Ironically, both rappers are still competing posthumously.

Last week, the BMW that Tupac was riding in when he was shot dead also went on sale for $1.5 million.
