22-52 Edward Humes, Pulitzer Prize Winner, "The Forever Witness"

In a long-form feature from Tech Nation, it’s Pulitzer Prize-winning author, Edward Humes, with “The Forever Witness ... How DNA and Genealogy Solved a Cold Case Double Murder.” We get an object lesson in the Three Ages of DNA from a forensic investigation standpoint, and while it reads like a fast-paced Cold Case on steroids – it provides details no fiction writer would dare to make up, including the unexpected involvement of the famous true crimes writer, Ann Rule, and a person whose DNA skills are familiar to fans of the PBS documentary series, “Finding Your Roots with Henry Louis Gates, Jr.”
