Published in its April 1995 issue, "Vibe" magazine's January interview with Tupac publicized his suspicions that individuals at the record studio, including Biggie and Puffy, had aided the November 1994 attack. Interviewed in response, Biggie and Puffy denied roles in the attack, and Biggie called it "crazy" to say that "Who Shot Ya?" was about Tupac. Still, citing the release's timing, and refusing to "hide behind the facts," Tupac created the now infamous song "Hit 'Em Up," naming, taunting, and threatening Biggie and Puffy. Released in June 1996, another massive hit on the streets, it impelled rap's East–West rivalry to peak intensity. Questioned about its alleged provocation, Biggie reiterated that he had recorded "Who Shot Ya?" well before Tupac was shot.
