Police are investigating a shooting at 23rd and Jackson after gunfire rang out and cars sped from the area.

One possible victim in the shooting arrived at an area hospital by car after the 1:30 PM shooting but we don’t yet know if police have confirmed any connection to the 23rd and Jackson shots fired.

30 minutes earlier, a massive, student-led “Protest Against Police Brutality” march had passed through the area with hundreds of elementary and high school students included.

There is nothing to indicate that the shooting was related to the protest.

Police were examining a late-model Cadillac with damage from the gunfire in the parking lot behind the 23rd and Jackson Starbucks.

One witness told police the shooter was accompanied by three other young males. They reportedly left the scene in a red Camaro-type car with a black roof while the shooter ran from the scene, according to witness accounts.

UPDATE 12/8/14 1:45 PM: Police have confirmed details of the shooting initially reported by CHS and tell us that they have — as of yet — not been able to connect the man who arrived at Harborview with a gunshot wound to the scene at 23rd and Jackson. Police say the man arrived and walked into the hospital by himself with a gunshot wound to the lower back. We do not have information on his condition. Police also said both the suspect vehicle and a victim vehicle were seen speeding away from the scene. The car with the bullet hole being examined at 23rd and Jackson was apparently parked in the lot and not directly involved in the shooting. There have been no arrests.
