Common questions
What counts as physical evidence?+
Physical evidence is any tangible item, trace, or mark found during an investigation that can be examined scientifically. It includes biological, chemical, or physical objects recovered from a scene, a person, or associated with the case.
How is physical evidence different from what a witness says?+
Physical evidence has its own independent existence and can be examined scientifically. Witness testimony is verbal and depends on a person's account. Physical evidence can establish or disprove facts independently of what any witness recalls.
Can physical evidence be used in court?+
Yes. Physical evidence is admissible in both criminal and civil proceedings when it has been properly collected, preserved, and scientifically examined. This is why chain of custody matters.
