Police say a man had been kicked out of a party and returned shortly before 1:30 a.m. with a gun.
He started shooting, "prompting others to open fire," according to investigators.
Three weapons were recovered from the scene.
In all, six people were taken to the hospital, including a 17, 18 and 19 year old.
The younger victim is said to be in guarded condition, and the other two teens are listed as stable.
