Francis Joseph van ZandtThe Identification of Francis Joseph van Zandt
On July 24th, 2007, while attending the IAI conference in San Diego, CA, Michael Grimm Sr. and Michael Grimm Jr. introduced I.D. Enhancer Solution to Ted Robinson. While at the EVIDENT booth, Mike Jr. explained to Ted the properties of the solution and the benefits that were seen when using the solution to rehydrate desiccated ridge detail.

Ted explained that he was currently working with Odile Loreille at AFDIL in Rockville, MD in an attempt to identify mummified remains from a 1948 plane crash in Alaska. The remains consisted of an adult male's left arm and hand. The arm had remained with the wreckage of the aircraft atop a remote glacier in Alaska until its discovery in 1999 by private pilots Kevin McGregor and Marc Millican. EVIDENT provided a complete I.D. Enhancer Postmortem Kit to Ted Robinson to assist in his efforts at AFDIL. AFDIL Rocckville, MD
The condition of the hand did not indicate that any identifiable fingerprints could be recovered. An attempt to identify the arm in 1999 failed. When Ted Robinson began his fingerprint efforts, attempts at a DNA identification were ongoing. His intention was to rehydrate the tissue and attempt to recover any viable ridge detail.

Using the I.D. Enhancer Postmortem Kit provided by EVIDENT, Ted Robinson began his rehydration efforts. Amazingly, the ridge detail of the 59 year old remains began to appear after soaking in the solution. Each finger was monitored until it reached the desired rehydration level.

After rehydration, a series of silicone casts were made of each finger by Ted Robinson. These postmortem reproductions recorded a tremendous amount of detail. The successful rehydration combined with the reproductive abilities of the silicone provided ideal results. Postmortem reproduction silicone casts
Upon completion of the postmortem reproductions, Ted Robinson contacted EVIDENT. Michael Grimm Sr., a vice president at EVIDENT, is also a certified latent fingerprint examiner with over 40 years of experience. Ted, Mike Sr. and Mike Jr. all met at an IHOP in Charlottesville, VA on August 23rd, 2007. Ted provided the silicone reproductions and a series of known fingerprint records from 18 of the 30 plane crash victims. Mike Sr. assumed that the identification would take a few minutes. The quality of the reproductions from Ted were nearly perfect, but the known fingerprint records were of poor quality. Known fingerprint record from the National Maritime Center
In an attempt to reveal additional ridge detail which could possibly be compared to areas of the known fingerprint records which were actually comparable, Mike Jr. began efforts to digitally enhance the silicone reproductions recorded by Ted Robinson. Using a flatbed scanner, each finger cast was individually scanned into Adobe Photoshop. A series of basic enhancement techniques were used to provide a much clearer postmortem fingerprint. A majority of the victims had been excluded through either pattern type discrepancies or DNA exclusions, with four possible victims remaining. Digital enhancements with Photoshop
These newly enhanced postmortem fingerprints prompted a visit to the National Maritime Center in Arlington, VA for comparison with the original fingerprint records of the remaining four victims. Additional fingerprints were discovered upon inspection of one of the files. Upon examination, Michael Grimm Sr. was able to make a positive identification between the left thumb postmortem reproduction and the left thumb print of Francis Joseph van Zandt.

The identification of Francis Joseph van Zandt by Michael Grimm Sr. is the oldest known postmortem fingerprint identification on record. The world's oldest know postmortem fingerprint identification
