碩士 === 國立臺北大學 === 犯罪學研究所 === 102 === Many papers talked about rape. Most of the studies emphasize the factors of criminal motivation and the personal backgrounds of the offenders. However, serious quantitative researches are quite limited. In particular, there is a lack of studies on topics related to the criminal modus operandi. This research is to fill in this literature vacuums. We intend to explore the modus operandi of the sexual crime, including the criminal situations, the methods of the crime and the criminal motivation. Simultaneously, we intend to analysis the relationships between the criminal modus operandi and the criminal motivations. We also would explore the relationships between criminal modus operandi and the personal factors of the offenders, such as age, and the previous offenses. Data are collected from the court records in a northern city in Taiwan for three years, beginning 2011 and 2013. A total of 225 rape cases were located for analysis. The research conclude that: (1) there is a relationship between personal factors of the offenders and criminal modus operandi. For example, insane rape offenders seem to take criminal actions without careful planning. Moreover, they use weapons more often than regular rape offenders. The married offenders have negative attitude after their offenses. Often they denied their criminal motives. (2) The difference between the criminal motivations of offenders has much related to the criminal modus operandi, including the offenders with affective motivation have more diverse and violent modus operandi than other types. (3) The relationship between offenders and victims has much to do with the crime events, including the time of the offenses, the use of the weapons, and the methods of the crime. For example, the stranger relationship between the offender and the victims often take advantages of the situation when the victims are drunk. Similar relationship also found on cases where the offenders and the victims are acquaint with each other. The research also proposes a strategy of crime prevention for rape based on the above findings.
