TikTok star Brandon “Boogie B” Montrell was shot and killed by a stray bullet Friday while Christmas shopping in New Orleans with his grandmother, his heartbroken mom revealed — as she railed against the leaders of the Democrat-run city. Montrell’s mother confirmed Saturday that the 43-year-old social media personality and comedian was the man killed while sitting in a car parked in the Rouses grocery store in the Warehouse District around 4:07 p.m. the afternoon before. The devastated mom blasted crime in Louisiana’s most populated city — and the leaders who need to “do their jobs.”
