Forensic linguistics

Stefan Zweig committed suicide, in 1942. This is his suicide letter. Forensic linguistics is also about finding out if such a letter was written by the person who committed suicide.

Forensic linguistics is a branch of applied linguistics. It uses linguistics to help give evidence in a trial. One aspect of it is to identify a person by analysing the language that person uses. Other questions might be about finding the author of a text (or telling whether two texts were done by the same person).
