Ear print analysis
Ear print analysis is used as a means of forensic identification intended as an identification tool similar to fingerprinting. An ear print is a two-dimensional reproduction of the parts of the outer ear that have touched a specific surface (most commonly the helix, antihelix, tragus and antitragus). Ear prints and their use for identification were first discovered by Fritz Hirschi in 1965. Fritz Hirschi was the first to identify a criminal using this method, in Switzerland in 1965 and ear print analysis has also been successfully used to solve crimes in the UK and the Netherlands. In addition to identification, the height of an ear imprint at a crime scene may also provide investigators with information regarding the stature of the perpetrator.
In 2002–2005 the Forensic Ear Identification (FearID) research project commenced to analyse the use of ear print evidence in criminal investigations. The research project was sponsored by the European Union to study the effectiveness of ear prints to be used as evidence in criminal investigations. The project used ear prints from 1229 donors. The European Commission is currently trying to create a database that will set the worldwide standard for ear print analysis.
The reasoning behind the limited use of ear print analysis in modern day forensics is due to the complex nature of collection and analysis methods. There has been some success with ear print analysis but the collection methods of ear prints and the complexity of proving a print matches a specific ear makes the identification method unreliable.
Fritz Hirschi, from Bern, Switzerland, was one of the first people to use ear prints for identification, in 1965. Hirschi analysed two earmarks at the scene of a burglary in Bienne, Switzerland. The earmarks were then used to observe if there was a connection between a more recent burglary where two men were arrested. The two men had their ear prints taken to compare to the previous marks left at the first burglary. Hirschi discovered that one of the two suspects had an ear print significantly similar to the ear mark at the first burglary, convincing Hirschi that he was involved with the most recent burglary.
The creation of the ear print identification system (similar to the fingerprint identification system) was developed by a University of Leicester Professor Guy Rutty along with a private forensics company. The team presented its work at the American Academy of Forensic Sciences in Dallas. Rutty measured the ear and observed physical elements such as sex differences in the external auditory canal, where females have shorter canals than males. The discoveries by Professor Guy Rutty of physical variations in the human ear opened the field of identification methods using ear prints.
Ear prints have been used in criminal cases for identification in Holland, with more than 200 judicial cases. Ear print databases are common in Spain, with history of criminal sentences using ear prints as evidence.
The Forensic Ear Identification (FearID) research project commenced in 2002 to analyse the use of ear print evidence in criminal investigations. The project was sponsored by the European Union and was composed of nine institutes from the United Kingdom, Italy and Netherlands.
The project used 1229 donors who donated three left and right ear prints. The ear prints were collected using controlled methods. Donors pressed their ear up to a glass plate and were instructed to listen for a sound. Then the ear print was lifted with a black gel filter. The research project aimed to standardise a method of ear print collection and accurately depict the print an ear may leave at a crime scene. Analysis of the ear print included details such as shape, size, Darwinian tubercles, creases, moles, piercings and scars.
