Anonymous Correspondence & Extortion Notes

The primary aim of any examination of anonymous correspondence and extortion notes is to determine the origins of the document.  FDS has had extensive experience in undertaking forensic examinations of such aspects as the handwriting, printing, typewriting, inks, paper, impressions and fingerprints with a view to recovering any evidence in that regard.

It is important that any envelopes or other packaging associated with the correspondence not be overlooked for forensic examination as they may also bear very relevant evidence.

Just because an anonymous document does not bear handwriting or text does not mean that it does not necessarily contain valuable latent forensic document evidence.

Non-documentary items sent anonymously and/or as part of the correspondence should be considered for fingerprint detection and analysis.
