SAN DIEGO (KUSI) – Crews extinguishing a possible arson fire that tore through a Mountain View-area home Thursday morning found the bodies of three people apparently killed by the blaze. Flames and smoke engulfed the single-story house in the 300 block of South 38th Street for unknown reasons about 6:15 a.m., according to the San Diego Fire-Rescue Department. Neighbors told arriving firefighters that people were trapped inside the burning home, SDFRD spokeswoman Monica Munoz said. Crews found the bodies after forcing entry to the structure. “They appeared to have succumbed to injuries caused by the fire,” San Diego police Lt. Matt Dobbs said.
