Behavioral
While responding to a multi‑vehicle collision with fatalities, the scene was chaotic and time‑sensitive.
I needed to secure the scene, collect evidence, and document injuries while coordinating with EMS and law enforcement.
I quickly established a perimeter, used a checklist to prioritize evidence, delegated tasks to junior technicians, and maintained clear radio communication to avoid contamination.
All critical evidence was preserved, the chain of custody remained intact, and the investigation proceeded without delays, earning commendation from the supervising detective.

During a homicide investigation, the victim’s clothing required both DNA and trace fiber analysis.
I was responsible for collecting and preserving the clothing evidence while coordinating with the DNA lab and trace evidence unit.
I photographed the garment, used sterile tweezers to collect fibers, sealed each sample in separate evidence bags, and logged detailed chain‑of‑custody entries before transferring them to the respective labs.
Both labs reported high‑quality samples; DNA matched a suspect, and fiber analysis linked the suspect’s vehicle to the scene, leading to an arrest.

- Documentation quality
- Outcome relevance
- Failure to mention documentation
- Only generic teamwork statements
- Photographed and documented evidence
- Collected DNA and fiber samples separately
- Maintained detailed chain of custody
