Answer:
A Primary Source
Explanation:
Primary sources are described as sources closest to the origin of the information or idea under study. This kind of sources provide researchers with "direct", unmediated information about the object under study. An eyewitness experienced the events closer than any other source. However, the reporter that uses this kind of source must be careful with the witness statements, because sometimes the evidence can be affected by the events, and create a fanciful idea about them.
