Two firefighters were injured in a massive five-alarm fire in Stockton that forced nearby homes to evacuate. Crews were called to a mattress fire in the area of Union and Flora streets just after 9 p.m. Thursday night. Investigators say firefighters faced heavy flames when they arrived. About 400 mattresses were on fire in an open space about 100×100 feet large. The winds spread the flames to a warehouse and several nearby homes, including one home a block away from the scene.
