A suspicious fire broke out Thursday night at a used car dealership in El Cajon, about a block away from where another fire started at an abandoned dealership last week. The blaze at New 2 You Autos on El Cajon Boulevard north of Chase Avenue broke out some time before 9:25 p.m., according to El Cajon police. Heartland Fire & Rescue Division Chief Mike Chasin told reporters at the scene Thursday night that fire crews found suspicious chemicals on the second floor of the dealership, according to 10News. Firefighters took just 13 minutes to extinguish the blaze. While crews were battling the flames at the dealership, a man walked into an area Walmart with burns, Chasin told reporters. The man’s connection to the fire was unclear, but he was taken to a hospital. Arson investigators were sent to the scene. Last Friday morning, flames broke out at a vacant Mercedes-Benz dealership just a few hundred feet from New 2 You Autos, on the opposite side of El Cajon Boulevard. Fire investigators did not know last week what started that blaze, and it was unclear if the two fires were related.
