One member of Nicki Minaj’s touring crew was killed and another seriously injured early Wednesday morning following an altercation in Philadelphia, where rehearsals for Minaj’s upcoming trek were underway. The rapper tweeted, “Two members of my team were stabbed last night in Philly. One was killed,” “They had only been there for two days rehearsing for the tour.” De’Von Pickett, a roadie, was killed after an argument broke out at Philadelphia’s Che Bar & Grill. The suspect – allegedly an ex-employee of the restaurant – is still at large.
