DULUTH, Minn. (AP) – Authorities say a preliminary investigation has found no signs of accelerants at a fire that destroyed a historic synagogue in northern Minnesota. But further investigation will have to be done once the building is stabilized. Firefighters responded to the fire at the Adas Israel Congregation in downtown Duluth early Monday. Authorities say they have some idea where the fire began. Authorities say eight of 14 Torah scrolls stored in the synagogue were saved.
