At approximately 1520 hours, while enroute to Rehoboth Station 2 for a cover up, Sussex alerted Milton, Lewes, Indian River, Georgetown, and Memorial for a residential structure fire on Idaho Ct. in the Lewes local. Engine-Tanker 85-2 responded from Coastal Hwy & John J. Williams Hwy, arriving within minutes to find a single story, single family home with nothing evident. Crews from 85-2 found an extinguished fire on the "delta" side of the home. Ladder 82, Quint 70-4, and 82-3 arrived and completed searches, overhaul and checked for extension. Command scaled the response back to the units on the scene. Units stood by for a short time awaiting the fire marshal. Deputy 85 had the "Lewes" Command.
