A key characteristic of physical evidence is that it can be collected and analyzed. This type of evidence refers to material objects that can be observed and measured, which allows for a systematic examination in a laboratory or at the scene where it was found. This collection process is crucial in criminal investigations, as it provides objective information that helps to reconstruct events, establish timelines, and corroborate witness statements. While physical evidence may supplement witness accounts, it is not based on them; rather, it stands independently and can validate or challenge what is reported. Interpretation by an expert may be necessary to understand the implications of the evidence, but the evidence itself does not intrinsically require expert interpretation to exist or to be collected. Additionally, while physical evidence can be crucial, it is not always conclusive on its own; it may be part of a larger puzzle requiring corroboration from other sources or pieces of evidence.
