Update: Man Fatally Shot At Silicon Valley Concert

Mountain View police spokeswoman Shino Tanaka said the shooting happened late Friday night during Pittsburgh rapper Wiz Khalifa’s performance at Shoreline Amphitheatre. The unidentified victim was taken to a local hospital, where he died on Saturday.

Police rushed to the outdoor concert hall after receiving multiple calls that shots had been fired backstage there, but officers are still looking for suspects. They are asking concert-goers for photos or videos that might provide clues.

Tanaka tells television station KTVU that authorities do not yet know how a gun made it into the amphitheater, where patrons undergo security screening.

Wiz Khalifa has a performance scheduled for Saturday night in Chula Vista, California.
