Authorities say a failure of an electrical circuit is to blame for an early Monday morning fire that caused tens of thousands of dollars to a Salisbury home. The Maryland State Fire Marshal's Office said it happened shortly after midnight at a two-story home located at 26926 Shetland Court. It took the Hebron Volunteer Fire Department approximately half an hour to get the blaze under control. The fire caused an estimated $50,000 in damage to the structure and another $25,000 in damage to its contents. There were no reported injuries.
