Study Notes

Forensic Science Processes: Securing and Packaging Evidence

Forensic investigators collect various types of evidence at crime scenes.
Evidence can vary in size, from tiny fibers to large objects like vehicles.
Evidence needs to be preserved in the same condition as found.
Proper packaging prevents contamination and maintains integrity.
Different evidence types require specific packaging materials (e.g., tubes, containers, envelopes).
Evidence should be packaged separately, labeled, sealed, and documented.
Chain of custody is crucial; it's a record of evidence handling.
Evidence tape secures evidence, indicating any tampering.
Tape must be intact and signed by all handlers.
Fragile items like hair are put in bindles (folded paper).
Large items like clothing are bagged, TVs and computers documented.
Weapons are unloaded, cleared, and placed in secure packaging labeled "biohazard" if necessary.
Degradable substances (blood, plants) require special care (e.g., refrigeration, drying).
Arson evidence (accelerants) should be in containers preventing vapor escape.
Different agencies/labs may have specific packaging guidelines.
Proper handling preserves integrity.
