The Junior Forensic Investigators Society (JFIS) of ๐ฆ๐ง๐ ๐ช๐ฒ๐๐ ๐ก๐ฒ๐ด๐ฟ๐ผ๐ ๐จ๐ป๐ถ๐๐ฒ๐ฟ๐๐ถ๐๐ has successfully concluded the practical component of its ๐๐ผ๐ฟ๐ฒ๐ป๐๐ถ๐ฐ ๐๐ต๐ฒ๐บ๐ถ๐๐๐ฟ๐ ๐๐ฒ๐ฐ๐๐๐ฟ๐ฒ ๐ฎ๐ป๐ฑ ๐๐ฎ๐ป๐ฑ๐-๐ข๐ป ๐ง๐ฟ๐ฎ๐ถ๐ป๐ถ๐ป๐ด ๐ผ๐ป ๐๐ฒ๐ฏ๐ฟ๐๐ฎ๐ฟ๐ ๐ฎ๐ญ, ๐ฎ๐ฌ๐ฎ๐ฒ. This session followed the foundational online lecture, ensuring our members moved from virtual concepts to mastering the actual application of chemical principles in forensic science.
This intensive hands-on training was led by our expert lecturer, ๐ ๐ฟ. ๐๐น๐ถ๐ป๐ ๐๐น๐ฒ๐ฎ๐๐ฒ๐ฟ ๐. ๐ฅ๐ถ๐ฐ๐ฎ๐ฟ๐๐ฒ, ๐ฅ๐ ๐ง, ๐๐ฃ๐ง, ๐ฅ๐๐ต๐ง, ๐ ๐๐๐ฑ(๐๐๐ฅ), ๐ ๐๐ฆ(๐๐ฆ๐๐ฃ๐ถ), STIWNU-CCJE Faculty.

The session focused on the ๐ฟ๐๐ฅ๐๐๐ฃ๐ฎ๐ก๐๐ข๐๐ฃ๐ ๐๐๐จ๐ฉ, also known as the ๐๐๐ง๐๐๐๐๐ฃ ๐๐๐จ๐ฉ, which is a forensic procedure used to detect gunshot residue (GSR) on a person's hands. Participants practiced the meticulous ๐๐๐ง๐๐๐๐๐ฃ ๐พ๐๐จ๐ฉ๐๐ฃ๐ ๐๐ง๐ค๐๐๐๐ช๐ง๐, which involves applying melted paraffin wax and absorbent cotton to create a solid, hardened shell on the subject's hands to trap gunpowder particles. Once the cast was hardened and removed, members moved to the ๐พ๐๐๐ข๐๐๐๐ก ๐๐๐จ๐ฉ๐๐ฃ๐ ๐๐๐๐จ๐, where a reagent is used to react with nitrates, causing a characteristic blue or blue-violet coloration if residues are present.

Beyond the laboratory techniques, agents were trained in the critical administrative aspect of forensic science: maintaining the ๐๐ต๐ฎ๐ถ๐ป ๐ผ๐ณ ๐๐๐๐๐ผ๐ฑ๐. Participants were taught how to properly fill out ๐ฆ๐ฎ๐บ๐ฝ๐น๐ฒ ๐๐๐ถ๐ฑ๐ฒ๐ป๐ฐ๐ฒ ๐๐ฎ๐ฏ๐ฒ๐น๐, documenting essential Subject Information, Specimen Descriptions, and the precise details of the Collecting Officer. This training ensures that every piece of evidence handled by our future investigators remains legally admissible and protected from contamination.

A key highlight of the training was the evaluation of the test's ๐๐ถ๐บ๐ถ๐๐ฎ๐๐ถ๐ผ๐ป๐. Members discussed how the test can yield ๐ณ๐ฎ๐น๐๐ฒ ๐ฝ๐ผ๐๐ถ๐๐ถ๐๐ฒ๐ from environmental sources like fertilizers, to***co, or cosmetics. They also explored how residues can be naturally removed through ๐ต๐ฎ๐ป๐ฑ๐๐ฎ๐๐ต๐ถ๐ป๐ด, ๐๐๐ฒ๐ฎ๐๐ถ๐ป๐ด, or friction.
This critical analysis reinforced why modern courts often treat the paraffin test as weak evidence compared to advanced methods like SEM-EDX.
We extend our deepest gratitude to ๐ ๐ฟ. ๐๐น๐ถ๐ป๐ ๐๐น๐ฒ๐ฎ๐๐ฒ๐ฟ ๐. ๐ฅ๐ถ๐ฐ๐ฎ๐ฟ๐๐ฒ for his expert instruction and for challenging our members to uphold the highest scientific and ethical standards in every investigation.
We step forward with renewed dedication. As members of the JFIS, we remember to ๐๐๐ ๐๐๐๐!
