Police in Vallejo say they were handling one shooting when they got a call about a second in the middle of a sideshow.
Video shows people lighting a ring of fire as drivers did donuts in the middle of the intersection at B.W. Williams Drive and Lewis Brown Drive just after midnight.
When the shooting call came in, Vallejo Police had to ask Solano County deputies to respond.
Police say one man was shot and killed.
They believe the man was in a car, though it's not clear if he was part of the sideshow or just passing by.
Police haven't arrested anyone tied to the shooting, though four people were arrested for the sideshow.

Police broke up the crowd about 25 minutes later.
