The death toll of the Oakland, California warehouse fire has grown to 36. The local district attorney's office has now dispatched a criminal investigation team to look into the tragedy. The converted warehouse was known as the "Ghost Ship." It served as a venue for the artistic community. A rave concert was underway when the fire broke out. Some reports say a lot of wood was in the building, and that there were no smoke alarms or sprinklers. City records show the warehouse was under investigation in November for having an "illegal interior building structure." Officials are still looking for answers to what started the fire, and they said the death toll will likely rise.
