What type of evidence is provided when a cyclist's description of a suspect vehicle is substantiated by surveillance footage?

Corroboration is the process of confirming or supporting a statement or piece of evidence with additional information. In this scenario, the cyclist's description of the suspect vehicle serves as an initial piece of evidence, but when it is substantiated by surveillance footage, it acts to reinforce and validate that initial claim. This duality of information adds credibility to the cyclist's account, establishing a more robust foundation for the evidence presented in the investigation.

While direct evidence refers to straightforward proof that directly links a suspect to a crime, the situation here includes an external validation (surveillance footage) that supports the cyclist's observations rather than offering a direct connection to any crime. Circumstantial evidence indicates a conclusion that can be drawn based on the facts, but this situation is more about confirming an existing statement rather than inferring conclusions from indirect evidence. Testimonial evidence usually pertains to statements made by witnesses in court, and while the cyclist's description can be seen as testimonial, it is the corroboration of this testimony with visual proof that emphasizes its validity.
