About 50 police cars plus the FBI responded to the scene in the 1800 block of Deming Way. The victims have been taken to area hospitals, police said. The shooter was shot by police and has died.

The building was then cleared and declared safe; all lockdowns had been lifted. The motive for the shooting was not known. The building also houses Esker Software and other bussineses.
