When dried blood is found on a larger object that is transportable, an investigator should cover the stained area with paper and tape the paper to the object to avoid contamination. If the object that is stained is not transportable there are different ways that an investigator can collect the sample.
Q. Why is paper the best material for packaging evidence Why is plastic not good for packaging biological evidence?
Paper or Plastic? There’s a simple rule of thumb for deciding which type of evidence packaging—wet evidence goes in paper containers (wet evidence can degrade if placed inside plastic containers) and dry evidence goes in plastic. Items that could be cross-contaminated must be packaged separately.

Q. What is the purpose of packaging the evidence?
Evidence must be handled and packaged to minimize deterioration and contamination. The guidelines in this pamphlet will help achieve that goal. Evidence submitted must be in sealed containers whenever possible. Evidence tape is the preferred sealing method.
Q. What evidence goes in paper bags?
However, paper bags are best for other types of evidence, such as blood, saliva, semen, and other body fluid stains. Paper bags work well for both fresh and dried blood or semen stains, for example.
Q. Why should evidence bags be resealed and initialed every time they are opened?
Why should evidence bags be resealed and initialed every time they are opened?-They must know everyone who opened the evidence so they can prevent items forbeing inadmissible in court. 8. -Evidence could get lost because the crime scene could be so massive.
Q. What is the documented and unbroken transfer of evidence?
Chain of Custody – the documented and unbroken transfer of evidence; lists all the people who came into contact with an item of evidence. Physical Evidence – any object that can establish that a crime has been committed or can link a suspect to a victim or crime scene.
Q. How is an evidence bag opened and resealed?
Once an evidence collector places an item into the bag, they seal the bag shut with the self-adhering strip and it instantly closes all the way across. This adhesive is specially formulated so it creates an instant seal and cannot be pulled away from the plastic of the bag.
Q. Which evidence is small or transfer?
These are referred to as trace evidence, and can be transferred when two objects touch or when small particles are disbursed by an action or movement. For example, paint can be transferred from one car to another in a collision or a hair can be left on a sweater in a physical assault.
