Types of evidence

• All evidence from crime scene or necroscopy can be divided into two categories: testimonial and physical.

a. Testimonial evidence:

• It is based on statement made by witness and suspects.
• As they are given by humans, who are open to error, testimonial evidence cannot always be trusted. Though they should be ignored, they should be supported by tangible facts rather than left to stand on its own.

b. Physical evidence:

• It encompasses any object or observations of an object, that can be used to establish whether or not a crime has been committed. Or can provide or disapprove a link between crime and its victim or crime and suspect.
• It can be found in many forms, some of which are tangible and capable of being collected and other which can’t be collected, but rather need to be documented photographically. For example: If paint flecks are found adhering to fur near a patterned confusion on the exposed skin, then both the fur and confusion are of evidentiary value. Though it is possible to collect the paint flecks as sample of confused tissue, but the pattern of confusion can only be “collected” through documentation.
