GW Forensics Professor Helps Solve 60-Year-Old Mystery
By Julia Parmley Odile Loreille, a researcher at the Armed Forces DNA Identification Laboratory (AFDIL) in Rockville, Md., was working to identify an arm and hand found frozen in 1999 on Mount Sanford, Alaska, the site where Northwest Airlines flight 4422 crashed in 1948, killing 24 Merchant Marines and six crewmen. Sophisticated DNA extraction techniques were proving futile, however, since years of weathering made the DNA strands in the arm virtually unreadable. A coworker of Loreille’s, Mike Coble, Ph.D. ’04, recommended she contact Robinson, his former forensics teacher, for his assistance. Robinson, an expert on crime scene investigation, focused on the hand’s fingerprints as the key to resolving its identity. The problem was that after 60 years in the frozen tundra, there didn’t seem to be any prints left. “Even with a magnifying glass, I could see no fingerprint details,” he says. “I knew I had my work cut out for me.” Robinson tried out several different rehydration attempts on the fingers to obtain clearer fingerprints and traveled to AFDIL laboratories several times to examine and photograph the hand. Success came when Robinson used the KDL I.D. Enhancer Solution, a rehydrating method that involves soaking the fingers and checking on them hourly. The results, says Robinson, showed “remarkable detail.” He then photographed the prints, reproduced them using two silicon casts, and gave the copies to Mike Grimm Sr., and Mike Grimm Jr., employees of Evident Inc., distributors of the enhancer solution. The Grimms compared the finger¬prints with records at the National Maritime Center in Arlington, Va., and found a match: Francis Joseph Van Zandt, a 36-year-old Merchant Marine from Roanoke, Va. It is the oldest known identification to date. “When the identification was made, I got goose bumps,” Robinson says. “The hair on the back of my neck stood up. I was amazed that all our information and work came together.” Using novel DNA tech¬niques, Loreille was eventually able to obtain both mito¬chon¬drial and Y-STR DNA from the arm, which matched living relatives of Van Zandt, independently confirming Robinson’s findings. Robinson and his colleagues shared their techniques and success at the International Association for Identification Education Conference in Louisville, Ky., in August and plan to publish their findings in a forensics journal. Robinson says he also intends to share his experience and newfound knowledge with his students. “I was amazed at the confluence of the people and information to make the identification,” says Robinson. “This project involved innovative DNA techniques and fingerprint enhancements that will assist in the identification of other individuals in the future.”
