The search continues Tuesday for a Vermont man who disappeared months ago. Richard Gammell, 84, disappeared on Feb. 27 after leaving his home on Mountain Avenue in St. Johnsbury. His car was found near River Road. Vermont State Police say they’ve searched for him daily. That includes walking the banks of the Passumpsic River, checking points of interest, using an unmanned aircraft and a state police K-9. Police say searching was difficult until the ice broke up about two weeks ago. Yesterday, officers planned to use a helicopter to search the Passumpsic River.
