Waka Flocka Flame’s younger brother, KayO Redd, has passed away. Reportedly, the aspiring rapper was found at home on Sunday (December 30).

Few details have emerged about the cause of Kayo Redd’s death, with mixed reports pointing at suicide or a possible shooting. Redd’s final tweets were promoting his latest mixtape Red Kisses, which he dropped this summer. Before that, he released the YNS 2: Full Time Grind mixtape in 2012.

Waka’s mother and high-profile hip-hop manager Deb Antney confirmed the sad news on Twitter late Saturday evening, telling fans, “I just lost another son.”
