From The Journal of Improbable Research:
“An earprint is an impression of the external ear. House breakers may leave their earprints inadvertently when they listen at doors and windows to check if there is anyone inside before breaking and entering a premises. Owing to uniqueness and individualistic characteristics of the human ear, earprints can be used as evidence to link a criminal with the crime. In the recent past, many suspected thieves have been convicted and several burglaries linked due to the presence of similar earprints.”
So writes Professor Kewal Krishan of Panjab University, India, in ‘Identification: Prints – Ear (Earprints)’, in the Encyclopedia of Forensic and Legal Medicine (Second Edition) 2016.
