TriggerPro gun swab kits are an example of “touch DNA” technology, which is an evidence gathering approach that attempts to collect viable DNA samples from small quantities of skin cells that remain after an individual has touched objects or places. The traditional method of gathering touch DNA evidence involves using a sterile swab moistened by distilled water. The pilot project was designed to examine the effectiveness of swabbing firearms to collect DNA samples capable of connecting individuals to firearms. The evaluation of TriggerPro is based on a comparison of two forensic methods: fingerprinting firearms versus collecting touch DNA samples from firearms using TriggerPro gun swabs. CCJR evaluation findings are summarized in this report.Crime prevention -- Causes of crimeLaw enforcement -- PolicingReport
