(AP) - Authorities in  Sun Valley say someone with access to administrative computers entered a fire station and deleted electronic documents that are the kind typically used in a forensic audit to catch financial wrongdoing.  Mayor Dewayne Briscoe says someone logged in at the Elkhorn Fire Station and targeted specific dates. The Idaho Mountain Express reports that Briscoe made the statements at a City Council meeting Thursday, but the deletion of files took place in February and March. Financial irregularities prompted the city in March to announce a forensic audit of all city departments that started Wednesday. Briscoe says the audit might identify who deleted the electronic files. Sun Valley Police say the investigation has been turned over to the Idaho Attorney General's Office.
