Silvia Pettem (www.silviapettem.com) is a longtime historical researcher, newspaper columnist, and author of more than twenty books. After decades of work for individuals and governments, her life took a new turn in 1996, when she stumbled upon the gravestone of a Jane Doe -- a murder victim from 1954. Pettem then applied her research skills to both old-fashioned detective work and the power of the internet by entering into a partnership with her local sheriff and with forensic experts of the Vidocq Society to successfully determine the young woman's identity. Pettem chronicled their work in Someone's Daughter: In Search of Justice for Jane Doe. In 2008, the Boulder County Sheriff's Office gave Pettem a Sheriff's Commendation Award for doing the "lion's share of the research" on the Jane Doe case. Then, in 2010, the Vidocq Society presented her with its Medal of Honor and made her an associate member. In addition, Pettem became a longtime volunteer in the Detectives Section of the Boulder Police Department and is a recent recipient of the City of Boulder's Lifetime Achievement Award. She also is a NamUs instructor in classes sponsored by the Colorado Bureau of Investigation -- expanding her expertise and working with colleagues all over the country.
