Answer 1

A) Follow standard lab procedures. To properly collect and submit evidence such as blood, hair, fibers, and other trace evidence, it is important to follow standard lab procedures, package and label the evidence appropriately, document the chain of custody, and use secure transportation methods.

Step-by-step explanation:

Proper collection and submission of evidence such as blood, hair, fibers, and other trace evidence is crucial in forensic investigations. Here are the recommended steps:

1. Follow standard lab procedures: This includes wearing appropriate protective equipment, using sterile tools, and ensuring a clean and controlled environment.
2. Package and label evidence: Each type of evidence should be stored separately in a suitable container, such as a paper bag or sealed envelope. Labeling should include a unique identifier, date, and location of collection.
3. Document the chain of custody: Record every person who handles the evidence, their role, and the date and time of transfer. This helps maintain the integrity of the evidence.
4. Transportation: Use secure and specialized transport methods, such as sealed and tamper-evident containers or mailing options specifically designed for forensic evidence.

Following these procedures ensures the preservation and integrity of the evidence, enabling accurate analysis and supporting legal proceedings.
