The SPDBlotter reports:

On December 6th at approximately 11:30 P.M., multiple units from the South Precinct responded to a large disturbance involving over 150 juveniles at a event in the 7000 Block of 32 Avenue South. … A short time later, officers responded to Harborview Medical Center where a gunshot victim had been taken. The victim stated he had been shot in the 4600 block of S. Othello and gave a suspect vehicle description of a white American car. Officers responded to 4600 S. Othello and located shell casings as well as damage to a residence and the victim’s vehicle.

It’s believed the two incidents are related. The Seattle Times has a bit more.
