The cause of a fire that erupted early Wednesday morning and destroyed Bisbee City Hall remains under investigation by the sheriff's department, while local officials are working to relocate public services. Robert Smith, interim city manager, said temporary offices are being set up at the Cochise County government complex on Melody Lane for some of the city’s functions. He said public meetings of the city council, commissions and boards, will be held in the county Board of Supervisors meeting room at the complex. “We’re working very hard to try and avoid disrupting the schedule for meetings,” Smith said. “The Supervisors meet in the morning and most of our meetings are in the evening so it works out.”
