This is the website for R. Brent Ostrum, D-ABFDE, Forensic Document Examiner.  I am a practising forensic scientist with over thirty years experience at the federal level in Canada.  This site provides information about forensic document examination and evidence evaluation, in general.  While much of the commentary pertains to Canada it is not specific to only that locale, unless indicated.  In fact, most topics covered are not at all jurisdiction-dependent, simply because forensic science itself does not, and should not, vary by location.  Legal issues, on the other hand, are often very specific to a particular jurisdiction and when my posts touch on those things the information will reflect it, as appropriate.

Please make a selection from the menu shown above.

If you have any difficulty finding information you require, please contact me directly and I will try to help.
