What type of evidence is used to convict someone of arson?

To convict someone of arson, evidence typically includes eyewitness testimonies, surveillance footage, and forensic analysis of the fire scene. Investigators may also look for accelerants, unusual burn patterns, and the presence of ignition devices. Additionally, circumstantial evidence, such as motive or opportunity, can play a critical role in establishing intent. Expert testimony from fire investigators often helps to clarify the cause and origin of the fire.
