Title: Fingerprint Analyst 1, Fingerprint/Identification Unit Case ID Number: 20-00000

Examiner: Bracey-Ann Francis

01/15/2021 - Request received from Assistant United States Attorney John Joe, Miami, Florida.

As per our conversation, and per your request, the exhibits examined were as follows:

Exhibit 1 - It is a certified copy of a prior conviction containing fingerprints, labeled as: Fingerprints of Defendant, received from Assistant United States Attorney John Joe, bearing the name of the defendant Jane Doe in case number 20-00000, and other descriptive information.

Exhibit 2 - It is a certified copy of the Arrest and Booking Report containing what is labeled as Right Thumb Print, at the bottom right corner of the report, as well as a certified copy of a prior conviction containing fingerprints labeled as Fingerprints of Defendant, received from Assistant United States Attorney John Joe, bearing the name Jane Doe in case number 20-00000.

Exhibit 3 - It is a certified copy of a prior conviction containing fingerprints labeled as Fingerprints of Defendant, received from Assistant United States Attorney John Joe, bearing the name Jane Doe in case number 20-00000.

Exhibit 4 - It is a standard fingerprint card containing (10) rolled inked fingerprints and a set of plain inked fingerprint impressions, simultaneously taken at the bottom of the fingerprint card, which I collected from the defendant Jane Doe, at the United States Courthouse on January 2, 2020, at approximately 2:30 p.m.

The two fundamental principles of friction ridge identification are uniqueness and persistence, meaning each area of friction ridge skin is unique to one individual, and remains unchanged throughout that individual’s life barring any scars or intentional mutilation.

A known/inked print is the deliberate reproduction of the friction ridges located on the joints of the fingers, the palms, and the soles of the feet. Fingerprint impressions are obtained by rolling each finger in ink and placing it onto a contrasting background/fingerprint card.

My conclusions were reached using the Analysis, Comparison, and Evaluation - Verification (ACE-V) Methodology. The following is a description of the method used.

The Analysis Phase is performed to make the observation of the individual impressions. This includes the general flow of ridges; clarity of the ridges and unique characteristics present; and any distortion appearing within the impression. The examiner then determines if the impressions in question contain sufficient information to continue to the comparison phase.

The Comparison Phase begins when two or more impressions have been found suitable for comparison. The impressions are compared using a ЪУг inch magnifying glass by following the ridges in sequence to determine if the same ridge detail and characteristics are present and in the same relative space of location.

The Evaluation Phase is when an identification, exclusion, or inconclusive determination is made by the examiner.

In the Verification Phase, a second examiner conducts an independent examination following the ACE methodology described above, providing a quality assurance measure.

Examination Notes: On January 20, 2020, I examined three exhibits, which have since been marked Exhibit 1, Exhibit 2, and Exhibit 3, containing known inked impressions.

Exhibits 1 through 3 contain rolled fingerprint impressions, as well as a certified Arrest and Booking Report containing what is labeled as a Right Thumb Print at the bottom of the report in Exhibit 2. I used the plain impressions on Exhibit 4 to confirm the sequence of the rolled impressions in Exhibits 1 through 3.

The right thumb fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location. When analyzing the right thumb, specifically on Exhibit 2, directly in front of the left delta, located in the center of the typlines, which is a point of divergence that surrounds or tends to surround the pattern area of the fingerprint, I found an enclosure, immediately followed by a bifurcation. After the bifurcation, there are two continuing ridges leading to the core area of the fingerprint. It was consistent with the #1 finger (right thumb) on the standard fingerprint card, Exhibit 4, of the rolled impressions of the defendant.

The right index fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location.

The right middle fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location. When analyzing the right middle finger, specifically on Exhibit 3, above the core area of the fingerprint pattern, I found a ridge ending. After the ridge ending, there is a bifurcation, which is followed by another ridge that comes to an end in the middle of the pattern area. These findings are consistent with characteristics in the same space of location on finger #3 (right middle) as on the standard fingerprint card Exhibit 4 of the rolled impressions of the defendant.

The right ring fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location. When analyzing the right ring finger, specifically on Exhibit 1, directly below the core of the whorl pattern, I found a bifurcating ridge. Below that bifurcating ridge are two continuing ridges, which lead towards the center of the two deltas.

The right little fingerprint impression(s) on all exhibits reveal loop patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location.

The left thumb fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location.

The left index fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location. When analyzing the left index finger specifically on Exhibit 3, directly in front of the right delta of the whorl pattern, I found a continuing ridge characteristic. In front of the continuing ridge is an enclosure that is followed by a bifurcation. In front of the bifurcation, there is a continuing ridge, which leads to the core area of the fingerprint. The unique characteristics found are consistent with the #7 finger (left index) on the standard fingerprint card Exhibit 4 of the rolled impressions of the defendant.

The left middle fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location.

The left ring fingerprint impression(s) on all exhibits reveal whorl patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location.

The left little fingerprint impression(s) on all exhibits reveal loop patterns: with similar size, shape, and flow of ridges, displaying the same minute ridge characteristics and detail in the same space of location.

Results of the Examinations: The fingerprints presented on the certified prior convictions referenced above as Exhibits 1, 2, and 3 received and marked, respectively, by Assistant United States Attorney John Joe, are the fingerprints of one and the same individual as on the standard fingerprint card marked as Exhibit 4 by Assistant United States Attorney John Joe, which I collected from the defendant (Jane Doe). A second Fingerprint Examiner conducted an independent examination and reached the same conclusion that all fingerprint impressions were made by the same individual.
