The correct answer is: a) One count of Arson in the noncampus category
Arson is any willful or malicious burning or attempt to burn, with or without intent to defraud, a dwelling
house, public building, motor vehicle or aircraft, personal property of another, etc.
Additionally, although the incident occurred at an off-campus residence, the Greek residence is associated with the school and therefore counts as Clery geography. Read more about Clery geography here.
It is important to note that some jurisdictions have specific rules that state that a fire is not to be classified as Arson unless and until a fire marshal makes a determination of malicious burning.
However, the Clery Act’s Arson definition does not require that any findings be made by a fire official before classifying an incident.
