OAKLAND -- A confrontation between two groups who had attended the Oakland First Friday event erupted into gunfire Friday night leaving an 18-year-old man dead and three other people, including a 17-year-old boy wounded, police said Saturday.

Killed was Kiante Campbell of Oakland.

The wounded included the 17-year-old Oakland boy, who police said was a friend of Campbell's, a 24-year-old Oakland woman and a 29-year-old San Francisco woman.

None of their names were released.

Police said the women were not part of the confrontation and were hit by stray bullets as they walked in the area.

The shooting happened about 10:49 p.m. in the parking lot of a beauty supply business in the 2000 block of Telegraph Avenue, which is between 20th Street, also known as Thomas L. Berkley Way, and 21st Street in the Uptown district.

Officer Jason Andersen said Campbell, the 17-year-old and some other people with them had been at the event since about 9 p.m.

For still unconfirmed reasons their group got into a confrontation with another group of people at the parking lot.

"It's unclear what (the confrontation) was about but it turned to gunfire," Andersen said.

Campbell died at the scene. The 17-year-old got his own transportation to a hospital in another city and the women went to another hospital. None of their wounds were life-threatening and all were expected to be treated and released by Saturday if they have not already

been, police said.

No arrests have been made.

There were scores of people in the area when the shooting happened but no other injuries were reported. The First Friday event is a monthly street festival with art exhibits, live music and food trucks on Telegraph Avenue in the Uptown district.

Official First Friday events are scheduled to end at 10 p.m., but patrons often remain in the area to go to local bars and clubs. There was no estimate of how many people were still in the area when the shooting happened.

The festival started as an offshoot of the Oakland Art Murmur, where local galleries and studios open to the public, but as the event grew, it moved away from Art Murmur's mission, said Executive Director Danielle Fox.

"We actually thought it was getting a little too crowded about a year ago, and so we stopped holding our little craft fair," Fox said. "We left a little vacuum, and into that stepped the city and a new organization (Oakland First Fridays)."

Art Murmur still runs its art walk event through the galleries and studios, but is no longer involved in the street festival, Fox said. The galleries were closed at 9 p.m. Friday night -- almost two hours before the shooting -- and Fox said she had left by about 9:20 p.m.

"It's not the mission of our organization to throw street parties or have rock festivals, but the city felt that it was important, and the business district felt that it was important," Fox added. "In the long run it's good for Oakland and it's good for the economy, as long as it stays safe."

Police said that many who had attended the event, which is spread out over a several-block area, may not even have been immediately aware a shooting happened.
