  • Unexpectedly moved (permanently or temporarily);
  • Uncharacteristically avoided the Central Park area;
  • Withdrew from social or family activities;
  • Missed work or scheduled appointments;
  • Showed suicidal gestures or attempts;
  • Showed Interest or special attention to the media coverage related to Marrisa Shen’s death; and/or
  • Increased or decreased his or her drug and/or alcohol use.

Criminal Profiling

IHIT investigators are using criminal profiling to help solve Marrisa Shen’s murder. Criminal profiling is an investigative tool used within the law enforcement community to help solve violent crimes. Criminal profiling is a logical, systematic approach for analyzing behaviour. The analysis is based on a review of evidence from the crime scene and from witnesses and victims. The analysis is done from both an investigative perspective and a behavioural perspective. The analysis can provide insight into the characteristics and traits of an unknown offender. Criminal profiling can also provide investigative suggestions and strategies for interviews and trial. However, a criminal profile cannot replace a thorough investigation. The accuracy and detail of a criminal profile is limited by the accuracy and detail of the information on which it is based.

Criminal profiling services can assist in the investigation of interpersonal violence. Criminal profiling is suitable for single-incident or serial cases with one or more victims, including but not limited to:

  • Homicides;
  • Kidnapping, including infant kidnapping;
  • Sexual assault;
  • Child molestation and abuse;
  • Hostage taking;
  • Bombings;
  • Arson;
  • Threat cases; and
  • Extortion.

Our criminal profilers are experienced investigators with extensive training in behavioural analysis. They have been certified by the International Criminal Investigative Analysis Fellowship (ICIAF) or the Association of Law Enforcement Profilers (ALEP) to provide analyses of criminal behaviour.

Our criminal profilers are actively engaged in this investigation and have developed a criminal profile of the person responsible for Marrisa Shen’s murder. Investigators will be sharing a partial profile on this website in the upcoming weeks.
