>>>>1. Direct evidence (evidence that supports a conclusion
of fact without inference)
OR
2. Circumstantial evidence (evidence that requires inference
to connect it to a conclusion of fact).
Physical Evidence - ANSWER >>>>May be more reliable

Types of Pattern Evidence - ANSWER >>>>(fingerprints,

Practitioners would offer a conclusive opinion that the known
and questioned item came from a common source to a
reasonable degree of scientific certainty.
The ability to associate an item of evidence to a sole, unique
source is currently being hotly debated. - ANSWER >>>>True
,What does DNA testing use? - ANSWER >>>>Statistical
occurrence of discrete pieces of genetic material or alleles.
Can physical evidence that is identified corroborate testimony,
place a subject at a scene, and be useful in a variety of ways

Chain of Custody - ANSWER >>>>Proof that evidence
collected during an investigation and the evidence ultimately

ANSWER >>>>Forensic Practitioners
What is important for a witness to know about cross
