Tupac crime scene investigator believes Sean “Diddy” Combs is connected to the rapper’s 1996 murder

Tupac Shakur crime scene investigator Sheryl McCollum believes Sean “Diddy” Combs is connected to the rapper's 1996 murder and his previous shooting in 1994.

“For me, the whole thing started in 1994 – when Tupac was shot for the first time,” McCollum, who was involved in Shakur's death in 1996, told New Nation on Friday.

The “All Eyez On Me” hitmaker was shot dead during a robbery at New York's Quad Studios in Times Square – at the same time Sean “Diddy” Combs was in the studio with an entourage of about 40 people.

“You don’t have to shoot someone five times to steal their jewelry and money,” McCollum explained.

“Sean 'Puffy' Combs and his 40-man entourage? Unharmed. Unthreatened.”

“How can it be clear to anyone that one person is being robbed and the other 40 are not? Who would have had more money and jewelry? Forty.”

After the shooting, Shakur openly accused Biggie Smalls (aka the Notorious BIG), his label Bad Boy Records, and the label's founder, Combs, of being involved in the incident because they reacted calmly when he walked into the studio with blood hobbled towards him.

“Nobody came to me. “I noticed that no one was looking at me,” he recalled to Vibe magazine in 1995.

“Puffy stepped back too. I knew Puffy,” he said. “He knew how much I had done for Biggie before he came out.”

Shakur was murdered two years later in a drive-by shooting as he left a boxing match at the MGM Grand in Las Vegas.

“Both times Tupac Shakur was shot, he was trapped in something,” McCollum told NewsNation on Friday.

“He's trapped in an elevator, and then he's trapped in a car. There’s literally nowhere to run.”

“However, ironically, there is no video footage in either scene,” she added. “To me it means that someone close to you knows where you are on that day, at that time and in that place.”

“That shrinks your suspect pool pretty significantly, in my opinion. Only a handful of people would have known where he was on those two days.”

Of course, Combs, 54, and Biggie vehemently denied any connection to Shakur's death. Ironically, Biggie was killed in 1997 and the case went unsolved.

McCollum expressed her theory after Page Six exclusively reported in July that Shakur's family was considering filing a wrongful death lawsuit against Combs.

“People from Diddy’s past are coming forward and providing information,” an insider told us.

The family hired attorney Alex Spiro, who has worked for Elon Musk and Megan Thee Stallion, to investigate.

The legal action came after it was revealed that the man currently charged in Shakur's death, Duane “Keefe D” Davis, had suggested in a 2009 interview with Las Vegas Metropolitan Police that Combs was plotting to kill Shakur of one million dollars.

Combs, of course, is already behind bars awaiting trial on sex trafficking and racketeering charges.
