A Clearlake woman and her dog died in an apartment fire at the Clearlake Commons Apartments Sunday morning. The fire burned part of one bottom-unit in a four-unit building of the apartment complex. Authorities responded at approximately 6:30 a.m. after the victim’s upstairs neighbor reported that her smoke detector was going off. Fire personnel contained the fire within 10 minutes after arriving on the scene. No damage was reported to other units. The cause of the fire and the woman’s death is under investigation.
