Friday night's shooting at a municipal building in Virginia Beach killed 12 people. Most were city employees with a length of service ranging from 11 months to 41 years.
"They leave a void that we will never be able to fill," City Manager Dave Hansen said Saturday morning.
Officials identified the shooter as DeWayne Craddock, 40, a 15-year public utilities engineer, who was a current employee at the time of the shooting. He died after what Virginia Beach Police Chief James Cervera called a "long-term large gunfight" with police officers.
Virginia Gov. Ralph Northam has ordered flags to be flown at half-staff over the state Capitol and called for all local, state and federal buildings to honor the victims. Flags will remain lowered until the evening of Saturday, June 8.

Rapp marched with the band as recently as St. Patrick's Day, and Roberts said, "Chris was reserved but very friendly, quietly engaging members one on one after our weekly practices. Even though we didn't have time to get to know him better, we shared a love for music that created an immediate bond."
