Tourists and locals captured images of the iconic Oceanside Pier Friday, one day after a devastating blaze erupted at the end of the structure. "We were in the middle of actually re-doing the concrete part," said Mayor Esther Sanchez. "That's like a $40 million dollar project. To have this happen, we're all brokenhearted." She said she's already gotten calls from state and federal leaders, offering their support in rebuilding the pier. Friday firefighters remained at the scene, watering down hot spots. The fire appears to have started in the old Ruby's Diner. So far, investigators have not determined what sparked the fire. The ATF is assisting in the investigation. Oceanside Fire Chief David Parsons said fire crews from multiple agencies worked through the night and were able to save 90% of the pier.
