Netflix’s hit sports documentary series Untold kicks off its fourth season with an in-depth look at the career of NFL star quarterback Steve “Air” McNair and his 2009 murder at just 36 years old. As TIME wrote back then, McNair had an “outstanding” 13-year NFL career but “sadly, what we’ll most remember about Air McNair is the shocking way in which he died.” He was found dead in his Nashville apartment on July 4, 2009, lying next to his mistress, Sahel “Jenni” Kazemi, a Dave & Buster’s waitress.
