http://www.10news.com/news/sources-...-diego-county-has-a-suspicious-ignition-point Team 10 sources say all but one of the fires that have been burning across San Diego County have a suspicious ignition point. 'Fire bugs' is the term being used inside the fire agencies. Sources say the fires started in a way that were not normal -- there were no sparks from a lawnmower or car engine, no thrown cigarettes and no cars involved. One source, a long-time arson investigator who is now retired, told us that CAL FIRE has a crack investigative team that will be looking closely at physical evidence and talking to witnesses to try to determine exactly how these fires started. The San Diego Fire Department also has an investigative team that will be looking into this. Locals will be asked if they saw anything suspicious or noticed strange activity in their area. The Carlsbad Police Department has already established a Tip Hotline for the Poinsettia Fire. Anyone with information can call (760) 602-7599 or send investigators an email. Fire crews have been battling nine fires across the county. No one has been injured but homes have been lost. Gov. Jerry Brown declared a state of emergency on Wednesday, clearing the way for more resources to help local firefighters.
