November
Examination of Bloody Friction Ridge Impressions - Webinar
11/25/24 - 11/25/24
Online

Blood matrix can be one of the more difficult factors affecting the interpretation of friction ridges. Owing to its unique composition, blood creates many unusual artifacts in friction ridge impressions. We will examine the range of bloody impressions from liquid, to tacky, to nearly dry. Furthermore, we will examine the typical characteristics that manifest in bloody impressions. We will watch the moments blood impressions are deposited and what happens to them as they dry. Finally, we will review the literature and research regarding ‘activity level’ statements such as if a bloody impression was made in blood or made with blood.
