What type of evidence is NOT commonly used in criminal investigations?

Presumptive evidence, while it has its place in the investigative process, is not as commonly utilized in criminal investigations compared to the other types of evidence. This type of evidence refers to conclusions drawn based on certain facts that suggest a likelihood of a particular circumstance or fact being true, rather than providing direct proof.

In criminal investigations, investigators rely heavily on more concrete forms of evidence. Digital evidence includes data from electronic devices, which has become increasingly prevalent due to the rise of technology. Physical evidence encompasses tangible items like weapons, DNA, and fingerprints that can directly connect a suspect to a crime scene. Testimonial evidence involves statements made by witnesses or victims that can provide crucial details about the circumstances of the crime or the identity of the perpetrator.

Each of these forms of evidence offers a stronger basis for investigation and prosecution because they can be more readily verified or disproven, whereas presumptive evidence can leave room for interpretation and is less definitive.
