Warren Spencer, CFDE/CFE, Certified Forensic Document and Fraud Examiner

Forensic handwriting analysis is used to determine " Who wrote it?" or in some cases to eliminate suspects by answering the question,"Who did not write it?" Questioned document cases often involve suspected fraud or forgery and signature verifications. Sometimes a questioned document case may be graffiti on a wall or a threatening note left in a mailbox or on top of a desk. Most forensic cases usually involve a signature, note, letter, contract or some other form of questioned document. LS Spencer and Associates provides handwriting examination services in cases of disputed handwriting or questioned documents. They are located in the western suburbs of Chicago and provide handwriting examiner services nationwide as well as international.
