Virginia Beach officials have identified the 12 people killed Friday night when a lone gunman entered a municipal building and opened fire with a handgun.

Dave Hansen, City Manager of Virginia Beach, said that all but one of the victims were employees, most of whom he knew personally.

“Sixteen Hours ago the lives of 12 people were cut short by a senseless, incomprehensible act of violence,” he said at a press conference Saturday morning.

“All but one of the 12 victims were employees of the city of Virginia Beach. I have worked with most of them for many years. We want you to know who they were so in the days and weeks to come you will learn what they meant to all of us, to their families, to their friends and to their coworkers. They leave a void that we will never be able to fill.”

Hansen used Saturday’s press conference to focus on the victims as other officials provided few details about the suspected gunman.

Virginia Beach Police Chief James Cervera identified the gunman as DeWayne Craddock, who was employed as an engineer with the city's public utilities department for 15 years. Craddock died in a gun battle with police. Cervera declined to comment on a motive.

Cervera said this would be "the only time we will announce his name."

Among the victims, Laquita C. Brown from Chesapeake, who worked for over four years as Right-of-Way Agent. Mary Louise Gayle, a resident of Virginia Beach, served as a Right-of-Way agent for over 24 years and Alexander Mikhail Gusev, also from Virginia Beach, shared the same title for 9 years.

Officials offered little details surrounding the shooting other than police had found several more guns on the building property and at the suspect's home.

“We did recover additional weapons at the scene, I’m not at liberty to tell what those weapons are at this time. We also recovered additional weapons at the suspect’s home," Cervera said.

He would not comment on a possible motive but said that Craddock had still been an employee at the time of the shooting and was able to access the building using his security pass. He did note, however, that citizen would be able to enter the "open government building."
