One hundred years ago today, Thomas Jennings was ushered the scaffold … while Thomas Jennings’s fingerprints ushered in a new age of policework (pdf).
Hegemonic authority had been on a long march towards a forensic regime that could affix an oft-ephemeral identity to the profoundly corporeal body.
In the late 19th and early 20th century, investigative techniques and jurisprudence marched double time to keep pace with new techniques — from photography to the unwieldy system of Bertillonage.
A variety of American institutions — the U.S. Army, a number of prison systems — had begun systematically cataloging their respective inmates’ fingerprints in the preceding years, but it was in the Jennings case that the system really earned its whorls. It was the first U.S. murder case pinned on fingerprint evidence.
In September 1910, a Chicago homeowner in the present-day Beverly neighborhood surprised an intruder, and was shot dead. (pdf) In the course of the fight or the flight, the prowler splooshed his left hand into some wet paint on a railing.
Thomas Jennings, a paroled burglar, was arrested near the scene, and his fingerprints shown to match those left in the grieving Hiller household. A prosecution expert even gave a courtroom demonstration of dusting for prints.
This was as novel to judges as to jurymen, and given the dearth of other positive evidence against Jennings, the Illinois Supreme Court was called upon to deliberate upon the humble dactylogram. In the summer of 20111911, it stopped Jennings’ hanging just hours before it was to take place.
But its final word in December 20111911 only fitted the homebreaker’s noose.
We are disposed to hold from the evidence of the four witnesses who testified, and from the writings we have referred to on this subject, that there is a scientific basis for the system of fingerprint identification, and that the courts cannot refuse to take judicial cognizance of it …
Such evidence may or may not be of independent strength, but it is admissible, with other proof, as tending to make out a case. If inferences as to the identity of persons based on voice, the appearance or age are admissible, Why does not this record justify the admission of this fingerprint testimony under common law rules of evidence.
Courtrooms all around the world soon agreed, and within a generation the awesome investigative power of the fingerprint had fugitives going so far as to slice or burn off those incriminating little pads of flesh — the crime scene gold standard until the advent of DNA testing.
Jennings was hanged this date in a state-record five-man batch (the others, Ewald and Frank Shiblawski, Philip Sommerling, and Thomas Schultz, had all committed an unrelated murder together).
