Chris Lighty, the 43-year-old hip-hop mogul who has worked with some of the biggest names, died this morning in his South Riverdale apartment. At this time it is believed that he shot himself in the head. Lighty got into the music business around 1988 when he joined Russell Simmons at Rush Management. During his lifetime, he managed the likes of Mariah Carey, Busta Rhymes, Q-Tip, Missy Elliot, Sean "Diddy" Combs, and 50 Cent. He was also the founder and chief executive of Violator Management/Brand Asset Group.

According to AllHipHop, Lighty was going through a difficult divorce, and "had a cryptic auto-reply email message that indicated... he would be hospitalized for an undisclosed ailment as of last night."
