The cause of the fire at the Days Inn by Wyndham on Route 7 last month remains unknown, but the Ridgefield and West Redding Fire Marshal says the blaze started in the bottom of a refrigerator. Flames extended up the wall, and could have been an electrical anomaly. The fire was reported June 20th. While the hotel is in Ridgefield, Redding firefighters were first to respond. The sprinkler system was activated automatically. There were no reported injuries.
