Arsons crimes are increasing in a remarkable way in the whole world, its methods and motives are becoming more complicated with city development and the control of the materialistic values, there are arsons crimes happen for the insurance money, malicious or revengeful, or to hide theft and embezzlement, or an internal motive from a mental illness.
