This document discusses ear prints and their use in criminal identification and solving crimes. It provides details on ear anatomy and development. Ear prints are 2D impressions of the outer ear that can be left on surfaces. The first successful ear print identification of a criminal was in 1965 in Switzerland. The document then describes a 1983 murder case in Brno, Czech Republic where the murderer was identified through an ear print left on the victim's front door. Jan Holub was convicted based on a match between the ear print from the crime scene and his ear print. His conviction was upheld, and he was executed in 1986.
