VIDEO: A Glendale convenience store was completely destroyed by a first-alarm fire early Wednesday morning, according to the Glendale Fire Department. Glendale, Peoria and Phoenix firefighters were dispatched to the first-alarm fire around midnight near 59th and Montebello avenues. "Crews arrived on scene to find a mini mart fully involved, they made a very quick attack with ladder pipes, which is very hard to do on a defensive fire," said Ashley Losch with the Glendale Fire Department. The convenience store, Pronto Mart, was completely ravaged by the flames. Due to structural integrity and firefighter safety, crews are waiting until sunrise to search the structure and begin their fire investigation.
