BARNSTABLE, MASS. (WHDH) - One person died after a house went up in flames on Cape Cod Sunday night.

Firefighters responding to a 911 call from a passerby reporting a fire at 118 Lakeside Drive in Marstons Mills around 8 p.m. found flames tearing through a ranch-style home.

After knocking down the bulk of the fire, the Centerville-Osterville-Marstons Mills Fire Department says crews entered the house to fully extinguish the flames.

“I want to extend our deepest condolences to the victim’s family and loved ones as they confront this tragedy,” Winn said. “As we investigate the exact cause of last night’s fire, I also want to remind everyone in the community that working smoke alarms and home escape plans are some of the most valuable tools in surviving a fire.”
