They both got shot and died. Rumor has it, Tupac slept with Biggie’s ex-wife, Faith Evans and Biggie also set up a shooting Tupac was involved in earlier. So when Tupac died, everyone thought Biggie did it, and they also thought Suge Knight had something to do with it, because when you rweind Pac’s song, it says, “Suge Killed Me” or something like that. Idk, iot’s really stupid. Anywho, Biggie died after that and people think Suge killed him as well.
