The shooting took place just before midnight on Friday.
A witness told ABC7 that she saw teenagers who appeared to be gathered for a graduation party at a hookah bar near the corner of North Palm and Highland Avenue.
She said after the initial shooting a vehicle pulled into the gas station where she was pumping gas and a person inside opened fire there shooting two girls.
A statement from police confirmed the crowd of people was in the area attending a party.
There was a massive response from law enforcement which remained on-site on Saturday morning.
One report says the deceased is a 20-year-old male whose identity has not yet been officially confirmed.
No arrests have been made and a motive for the shooting is so far unknown.
