CRIME profile development.

Crime scene evaluations

Perpetrator able to access building without being identified or noticed as being out of place. Evidence of mutilation to the body. Significant overkill in perpetration of crime. Perpetrator had significant time to commit serious of acts in crime. Sexual arousal. Perpetrator had manipulated body and crime scene. Reasonable physical strength and mobility required to commit crime. Use of objects present at the crime scene (victim’s belongings) to perpetrate murder. No attempt to cover up DNA evidence. Words carved into the body may represent an attempt to communicate with either the victim, law enforcement, another individual, or himself. Alternatively, staging of crime scene should be considered. Summary of crime scene evaluations:  The victim’s morning routine, while structured and regular, did not involve a consistent pattern of leaving her residence. As such, a perpetrator would not know whether she would walk down the stairs or catch the elevator. That nature of the crime therefore indicates a blitz attack, with the crime indicating that the offender did not have a pre-determined plan to kill the victim, as indicated by strangulation with her bag strap. Further, while it may have been due to timing that the perpetrator was not recognised in the building, it must be considered that the perpetrator was able to access the building and not appear out of place. The behaviours of the perpetrator indicate both sexual and violent motivations, with both patterns of behaviour evident. Significant violence was used in committing the crime, including mutilation of the body post-mortem. The offender was sexually aroused at the crime scene and able to ejaculate to a mutilated and bloodied female body, indicating that sexual excitement was obtained from the murder. There are a range of differential diagnoses or explanations to account for this sexualised violence, ranging from sexual arousal towards the victim, through to paraphilic conditions such as sexual sadism or haematophilia (sexual fetish for blood). The perpetrator made no attempt to cover his DNA (e.g. semen and faeces). The role of defecating at the crime scene remains unclear, whether this was linked to fantasy, anxiety or other motives. The post-mortem behaviour by the offender, while partially a possible attempt to stage the crime scene, also involved targeted mutilation of breast and genital areas. This is considered to be an action above and beyond the need of a sexual crime, indicating excessive fixation and emotional disturbance.

Relevancy of research

Provide an overview of the relationship between mutilation of the body and sex crimes, including offender characteristics. Sexual crimes involving defecation. Post-mortem behaviour in sexual crimes. Strangulation as a means to murder.

Investigative or clinical opinion

This area may depend on the investigators or experts involved in the case, topics may include: Past sexual offenders in the local area. Similar instances of body mutilation. Theories of defecation in sexual crimes.

Methods of investigation

Interview all residents residing in apartment building and seek to eliminate on DNA. Develop a log of visitors who frequent building regularly and seek to exclude. Examine any other crimes that have occurred in the building, such as break and enter offences. Exclude as suspects. Complete thorough analysis of victim’s life, excluding former boyfriends. Examine previous sexual crimes in region with significant violence and that are unsolved.

Evaluation

Review any additional information that may be missing from the profile, such as forensic reports that have been completed yet not supplied. Summarise key information contained with the profile, placing the strongest emphasis on evidence-based conclusions. Undertake peer consultation and/or review in relation to the profile or the recommendations made before releasing the written document.
