According to Los Angeles police, Glo Gang rapper 600BossMoo killed a woman, believed to be his girlfriend, and then turned the gun on himself.
The murder-suicide went down Thursday in an upscale Woodland Hills apartment complex.
The murder victim had called the police right before her death, reporting 600BossMoo was brandishing a gun. When the police arrived they were both dead.
While Keef hasn't commented on his artist's death (and crime), 600Breezy has weighed in.
Last month Keef's rapper YNC Capo was killed in a carjacking.
RIP.
