Last month up and coming rapper Kid Cali was shot dead at a pool party hosted by former Chris Brown associate Kid Red [click here if you missed that].
A suspect has been taken into custody...
LAPD arrested a 19-year-old guy Saturday for the shooting death of Cali -- who was well-known on the L.A. rap scene.
Law enforcement sources tell us the fatal shots were fired during a fight between 2 rival gangs at the party. Two other people were shot, but survived. It's unclear if Cali was targeted or merely an innocent bystander.
