Investigators are putting together a clearer picture of the shootings, in which the victims were found in a car in the SoDo district, about three miles away from the shooting scene.
The sequence of events began shortly before midnight when officers responded to a 911 call about shots fired in the area of 4th Avenue and Jackson Street. When officers arrived they found dozens of shell casings but no victims or suspects.
As officers were searching the area for possible victims, another 911 call came in reporting a man in a car in the 5000 block of 1st Avenue South who had been shot, said Renee Witt of the Seattle police.
When officers arrived there, they found four people in a silver car in the Jack-in-the-Box parking lot. One of them, a 26-year-old man, was dead from a gunshot wound. Another person, a 22-year-old man, sustained serious but non-life-threatening injuries.
Follow-up investigation found that the shooting was preceded by an argument outside Club Volume on South Washington Street. When the victims drove away from that scene they were followed.
Near the intersection of 4th and Jackson, near King Street Station, a car pulled alongside the victims' vehicle and an occupant opened fire, hitting the two men sitting in front.
Moments later 911 dispatchers received the call reporting shots fired at 4th and Jackson. As police searched the area, the injured man drove the car about three miles away from the scene of the shooting to the 5900 block of 1st Avenue South.
Then came the second 911 call reporting their location of the victims' car. The 26-year-old was dead when officers arrived and the 22-year-old was taken to the hospital.
Two other passengers in rear seat of the car were not injured.
Homicide detectives investigated all three scenes and gathered evidence.
No suspect information is available at this time.
