There are three approaches used in comprehensive profiling of a perpetrator, namely: the Criminal Investigative Approach, Scientific Statistical Approach, and the Clinical Practitioner Approach. However, behavioral analysts use the criminal investigative approach to review and assess a criminal act (Malocco 74). For comprehensive profiles, investigators will have to look at the personality, personal life, residency, relationships, medical records, employment, digital information, and financial information of the perpetrator.
Concerning the case, the personality approach can be used to describe what type of person the offender is. In this case, he appears to be well organized. He kills after every three weeks. The fact that he attacks and kills his victims means that he may have a mental disorder or is motivated by anger, revenge or previous hardships and experiences. His residency may also be a motivating factor as the region is sparsely populated. Therefore, he can carry out his attacks without being seen (Hatton & Markgraf 1). Regarding relationships, he may most likely be single, or without a family which enables him to carry out the attacks without suspicion. He is most likely leading a secluded life.
Medical records can be used by investigators
to narrow down the number of people with reported mental disorders in the
region. The database can also be used for
comparison with DNA samples from the victims and crime scenes. The victim may
most likely be employed which is why he chooses to attack weekends at night. He
may or may not be using digital platforms to target his victims, depending on
the pattern of how he chooses his victim (Malocco 112). Financial information is also critical
for investigators to determine whether
the attacks are motivated by money.
However, in the case of Texarkana Moonlight Murders, that does not apply which
may lead investigators to other causes.
