Although the original purpose of the establishment of Eurodac did not require the possibility of requesting comparisons of data with the database on the basis of a latent fingerprint, which is the dactyloscopic trace which may be found at a crime scene, such a feature is fundamental in the field of police cooperation. The possibility to compare a latent fingerprint with the fingerprint data which is stored in Eurodac in cases where there are reasonable grounds for believing that the perpetrator or victim might fall under one of the categories covered by this Regulation would provide the Member States’ designated authorities with a very valuable tool in preventing, detecting or investigating terrorist offences or other serious criminal offences when, for example, the only evidence available at a crime scene are latent fingerprints.
