Why is evidence packaged separately and properly?
After evidence has been found and gathered, it must be protected. Each piece of evidence gathered is packaged separately to avoid damage and cross-contamination. Most dry trace evidence is placed in druggist’s folds, which are small, folded papers.
Why should evidence bags be resealed and initialed every time they are opened?
Any leaks in an evidence bag can result in deterioration, contamination, and loss of the sample. Our tamper-proof evidence bags can withstand wear and tear, they’re easy to write on, and they can’t be resealed after opening.

What evidence should be collected first at a crime scene?
Fingerprints (which also include palm prints and footprints) are another type of evidence that can tie individuals to crime scenes. Collecting fingerprints is a crucial process and should be one of the first things conducted when investigators arrive at the crime scene.
What are the different types of containers for evidence?
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.
What type of container should not be used to package blood evidence?
It is important to only place one item per container to avoid contamination and samples should not be placed in plastic containers. Samples shouldn’t be in plastic containers because if the sample is still damp the moisture from the sample can cause microorganisms that can destroy the evidence.
