Accidental whorls combine two or more different types of subgroups – the only one that does not apply in this combination is the plain arch – have two or more deltas and contain ridges matching the characteristics of a whorl subgroup. Glenn and Eric talk through various fingerprint stories from the news including the recent posting of a German minister's fingerprint. This ridge is cut or touched by an invisible or imaginary line. Between the loop formations is at least one recurving ridge within the inner pattern area.

There are only 3 general types of fingerprints, loops, whorls, and arches. Arch: a pattern in a fingerprint where a ridge runs from one side of the finger. This obstruction has two deltas with an invisible line in between, but no recurving ridge within the pattern is cut or touched. This whorl pattern has one or more recurving edges or a right-angle obstruction to the line of flow. This type of whorl also has two deltas with an invisible or imaginary line that touches or crosses at least one recurving ridge within the inner pattern area. Two separate, distinct loop formations make up a double loop whorl pattern.
A plain whorl has one or more ridges that make a complete circuit. Whether youre a practicing Latent Print Examiner or youre interested in forensics and true crime, the Double Loop Podcast is a weekly show featuring Glenn.
