Starting with 2Pac (Tupac Shakur), what is interesting that in his songs and interviews he talked so much about being murdered that he seemed obsessed (or paranoid?).
Shortly before his death he filmed the video clip for "I Ain't Mad at Cha", in which 2Pac was depicted in the afterlife, as some sort of angel in white.

On 7 September 1996, 2Pac was shot in a drive-by-shooting, and died 6 days later in hospital, according to some sources he would have survived his injuries, he even tried to escape the death trap (hospital).

There are some strange connections to Quincy Jones.
2Pac dissed Quincy Jones for strictly f*cking white women, “All he does is stick his dick in white bitches and make fucked up kids”, and then was seduced by Quincy’s Jewish daughter!
2Pac was dating Quincy’s daughter Kidada Jones at the time of his death. While she was in Las Vegas with Tupac for some reason Kidada Jones wasn’t in the car with him when he was shot, she claims that 2Pac didn’t want her to come along.
Even more suspicious is that Kidada describes 2Pac’s injuries as his cause of death.
See Tupac with his fiancée, Kidada Jones.

Did his mother, Afeni Shakur, really decide to take Tupac off life support on 13 September 1996: https://www.iloveoldschoolmusic.com/qui ... death-bed/
Griff – gay Quincy
A more indirect link is through Will Smith, who was made into a huge movie star by the Quincy Jones produced Fresh Prince of Bel-Air, through Smith’s wife Jada Pinkett, who was a friend of Tupac.
According to Professor Griff (of Public Enemy fame), Quincy Jones set up sex rings;
Quincy Jones recruited the lesbian Queen Latifah for a movie;
Quincy Jones also produced Tevin Campbell with something (?) gay;
2Pac refused to have sex with Quincy Jones that's why he was marked for death. 2Pac was engaged to Quincy's Jewish daughter Kidada Jones, who was a friend of Aaliyah that was engaged to Damon Dash (Jay-Z's business partner) when she died;
Puff Daddy (Sean Combs, Diddy) is also gay, and played a role in destroying hip-hop.

Quincy Jones ridiculed the idea that he wanted to have sex with 2Pac (Griff’s conspiracy theory isn’t supported by any evidence or even specific witnesses):
https://tvone.tv/6864/quincy-jones-smas ... m-the-90s/I’ve been called a blonde-lover, a pedophile, gay, everything. I don’t care, man. Imagine my daughter being engaged to Tupac and me trying to make love to him? And I’m not into no men, man. I’m a hard-core lesbian.
Notorious BIG
Tupac biggest rival was the Notorious BIG (Christopher Wallace, a.k.a. Biggie Smalls) who was likewise shot and killed in a drive-by-shooting in LA. At the time he was celebrating finishing his second “solo” album, released 16 days after his murder on 9 March 1997, prophetically called “Life after death”.

This song was unfortunately never released as a single, and could have been a motive for US authorities to murder Wallace.

For many Quincy Jones is best-known for producing Michael Jackson’s best-selling albums (who also died under suspicious circumstances for which his doctor was blamed). While Quincy wasn’t involved, Biggie collaborated with the King of Pop on "This Time Around", a song from Jackson’s HIStory album.
A more interesting Quincy link is that the Notorious BIG went to a Soul Train Awards after-party sponsored by Quincy Jones and Vibe magazine, after which he was murdered in the drive-by-shooting.
According to FBI Agent Phil Carson, Puff Daddy (Sean Combs, a.k.a. Diddy) was the real target, and the hitman was Amir Muhammad, godparent of the children of corrupt LAPD cop David Mack.
A more common conspiracy theory on who ordered the murder of Biggie, is Suge Knight, label boss of Death Row (that had 2Pac under contract), who allegedly ordered the hit from behind bars in retaliation for 2Pac’s murder. This theory was promoted by LAPD officer Greg Kading and others (including our wonderful media): https://allthatsinteresting.com/biggie-smalls-death
Russell Poole – Suge Knight, FBI
Former LAPD officer Russell Poole seems to be the best known “conspiracy theorist” on the murders of 2Pac and the Notorious BIG. The problem is that he has made so many insinuations that it’s more like an overview of conspiracy theories than a description of what really happened.
Poole died of a heart attack in August 2015, when he was working on a book about the murders…
Poole accused the corrupt LAPD cop David Mack along with his friend Amir Muhammad, of murdering Biggie on the orders of Death Row Records head Suge Knight, in retaliation of the murder of 2Pac.
Poole was ordered to stop his investigation on the case, and he retired from the LAPD in 1999: https://web.archive.org/web/20200227050 ... poole-dies
According to Russell Poole, David Mack was in the Bloods gang, like Suge Knight, and Mack was a frequent visitor at Knight's private parties
Poole's investigation inspired Randall Sullivan's book, Labyrinth: A Detective Investigates the Murders of Tupac Shakur and Notorious B.I.G., that was made into the film City of Lies (2018), starring Johnny Depp as Poole: https://en.wikipedia.org/wiki/Russell_Poole
Russell Poole has accused Snoop Dogg’s cousin Donald Smith (a.k.a. Lil ½ Dead) of murdering 2Pac, because he had stolen his song Brenda's Got a Baby that became Tupac’s first hit single.
This doesn’t make sense at all; Death Row co-founder Dr. Dre made Snoop Dogg (a family friend) a big rap star, and later made 2Pac into a superstar: https://web.archive.org/web/20170325184 ... d-2pac-056
Marion ‘Suge’ Knight claims that his ex-wife Sharitha Golden and former Death Row Records security chief Reggie White Jr. killed Tupac Shakur, but that he was the real target (he was in the same car as 2Pac).
Several people that accused White Jr. of 2Pac’s murder died in the past decade, including Pac’s ex-bodyguards Michael Moore, Frank Alexander and (the previously mentioned) Poole.
Bizarrely Russell Poole, who accused Suge Knight of Biggie’s murder, also agreed with Suge’s claim that he was the intended target of the 2Pac shooting: https://www.dailymail.co.uk/news/articl ... oting.html
John Potash claimed in his 2008 book The FBI War on Tupac Shakur and Black Leaders that the FBI was behind the murders of Tupac and Biggie.
According to Potash, the FBI wanted to end the rap culture of the ’90s: www.usmagazine.com/entertainment/news/2 ... r-w471171/
