Tate Suspect List


Suspects Eliminated By Fingerprints

Today fingerprints are fed into a computer and finding a match or not isn't a laborious or time-consuming process like it was in 1969 when the Tate and LaBianca murders were investigated.

So, just how did they narrow down fingerprints to streamline the process in the TLB cases?

The Henry Classification System was used categorize the different types of fingerprint characteristics that are made by friction ridges and furrows.

There are three main types of fingerprints, loops, whorls and arches. Within those three groups loops, which recurve back onto themselves to form the loops, are divided into radial loops that point towards the radial bone (thumb) or the ulna bone (pinky finger).

Whorls form circular or spiral patterns and are divided into four groups. Plain whorls are concentric circles, central pocket loops are loops with a whorl at the end, double loops that create an S-like pattern and accidental loops are irregularly shaped.

Arches make a wave like pattern that are either plain or tented. Tented arches rise to a sharper point than plain arches.

The palms of the hand also have distinct ridges and furrows. Another type of print is the chop. The chop is the side of the hand from the tip of the pinky finger to the wrist. The best example of where you might find the chop is if you were to place the sides of your hand on a window to block out glare while peeping.

No two people have the same fingerprints, even identical twins and no one person has the same fingerprint on more than one finger or thumb.
