Dr. Romano would describe cross-contamination on a crime scene as the unwanted movement of material from other sources to the physical evidence by contaminating the evidence.
What does contamination of evidence mean?
Contamination of evidence in a crime scene refers to a situation where there exists an unwanted modification to evidence that can affect the integrity of the original crime scene.
This unwanted tempering to the evidence can eliminate original evidence transfer, place misleading materials onto an exhibit or adulterate a sample.
For example, DNA evidence can be contaminated when DNA from another source gets mixed with the DNA relevant to the case as a result of someone sneezing or coughing over the evidence.
Investigators are to be very careful so that contamination of evidence at a crime scene does not occur as this would affect the result's integrity.
