Who is responsible for the collection of sexual assault evidence?

The collection of sexual assault evidence is primarily the responsibility of an expert during the medical examination. This is because such evidence collection requires specialized training and knowledge to ensure that evidence is handled properly without contamination, which is crucial for the integrity of any potential legal proceedings.

Medical professionals, such as sexual assault nurse examiners (SANEs) or forensic examiners, are specifically trained to conduct examinations in a way that prioritizes the victim's health and well-being while also adhering to legal standards for evidence collection. They know how to document injuries, collect samples, and preserve evidence in a manner that meets the necessary legal requirements.

While trained officers and first responding units play important roles in the initial response to an incident, including securing the scene and gathering initial information, they are typically not responsible for the detailed medical evidence collection, which requires the expertise of a medical professional. The victim, although central to the process, is not tasked with collecting evidence as it can be overwhelming and not within their expertise to do so effectively.
