What lies beneath?
Are thermal cameras the next step in law enforcement documentation of assault injuries?

I believe it would be fair to say that assault investigations are a daily occurrence for most law enforcement agencies. Techniques of observation are paramount to all levels of law enforcement investigation involving assaults which our profession is often called to investigate. Knowing what to look for and how to look for physical evidence helps to verify assault claims and has a major impact on how we proceed with cases. How can law enforcement document injuries that are internal or even advise victims they need to seek medical treatment if our abilities are limited? There may be a way in the near future where we could see the …show more content…

Contrary to popular belief, non-fatal and even fatal strangulations leave very few, if any, signs of external injury (Strack et al., 2014, p.88).

By contrast, choking is an internal blocking of the airway by a foreign object, but this is often used incorrectly to describe strangulation. Subtle signs and symptoms of strangulation are: headache, sore neck, sore throat, trouble swallowing, raspy/hoarse voice, breathing difficulty, vomiting, petechial hemorrhage, loss of bowel control and loss of memory (Strack et al., 2014, p87). A sore throat and/ or voice changes are present in 50-70% of evaluated cases (Foley, 2015, p89). Repeated acts of non-fatal strangulation lead to long term behavioral, neurological and psychological disorders (Strack et al., 2014, p87). Victims of strangulation can die hours or weeks later from a strangulation event if immediate medical intervention is not sought. A published study through the Journal of Emergency Medicine ( October 2008, 35(3), pages 329-335) showed that if a woman survives strangulation even once she is 700% more likely to be strangled again and 800% more likely to be killed later. The lack of physical evidence in strangulations has caused many to treat it as a minor incident, when in fact, they are some of the most lethal cases we will deal with (Gwinn, Strack, Mack., 2014,
