• Resumen

  • In this article the author discusses how fingerprint- and DNA-identification techniques helped to solve a mystery from a 60-year-old airplane crash. She provides an overview of the March 12, 1948 crash of Northwest Airlines flight 4422 into Mount Sanford in the Wrangell Mountains in eastern Alaska that killed 24 passengers, including merchant marines returning to the U.S. from Shanghai, China and Northwest crew members. Topics include the discovery of an arm in 1999 by former U.S. Air Force pilots Kevin McGregor and Marc Millican and the development of a DNA-identification technique by researcher Odile Loreille of the Armed Forces DNA Identification Laboratory in Rockville, Maryland, that uses a demineralization process to dissolve bone matrix for mitochondrial DNA (mtDNA) analysis.
