Techniques in CriminalProfiling

Criminal profiling works on the assumption that regardless of the severity of the crime,

offenders will display a certain similar pattern in their criminalactivities (Turvey, 2011). From

the vignette, the suspectedserialrapist has a pattern ofraping women at a particulartime attheir

homes. Previous techniques employed the use of eyewitnesses’ accounts but has changed with

time to whatis nowthoughtto be evidence leftat the scene. In this regard, the fingerprint

evidence is not only used in profiling an offender but also to provide evidence of the

perpetrator’s presence. In the same way, the offenders’ DNA tests are carried out on hair, fibers,

and other effects left behind to prove beyond doubt the accuracy of the findings. Also, computer

experts can even reconstitute erased hard drives to build up on the offenders’ online activities.
