Graffiti

Graffiti can occur anywhere, but the forensic examination of it often relates to the workplace and to crime scenes.  Graffiti can be produced using all kinds of media (for example spray cans, marker pens, writing pens and pencils, as well as sharp items by means of scratching) on all kinds of substrates (for example walls, doors, magazines, books, trains and cars). 

It is an area of handwriting examination which usually has a number of limitations but in which our forensic examinations can often still yield a useful result.
