What type of person typically provides information about an event or circumstance?

A witness is a person who has firsthand knowledge of an event or circumstance and can provide relevant information about it. Witnesses can testify to what they saw, heard, or experienced directly, making their accounts crucial for investigations or legal proceedings. They often play a vital role in establishing facts or details surrounding an incident, contributing to a clearer understanding of what transpired.

The other roles listed, while potentially involved in an incident, serve different functions. A suspect is a person believed to have committed a crime, while a bystander is someone who happens to be present at the scene but may not have direct information about the event. A victim is the person who has suffered harm or loss due to the incident. Witnesses, by their nature, provide objective accounts based on their direct observations, which is why they are essential for gathering accurate information about events.
