Police Chief James Cervera, speaking at a morning news conference, said it would be the only time his name is mentioned publicly by law enforcement. Craddock was killed in a shootout with police inside the building.
Craddock was an engineer at the Virginia Beach Department of Public Utilities for 15 years, police say. He worked in the city's water and sanitary sewers branch and was still employed with the department at the time of the attack, according to authorities.
Cervera declined to reveal the motive of the attack.
