On October 3, 1996 the body of 29-year-old Sharon Kay Hammack was found by a delivery driver in a field in Caledonia Township, Kent County, Michigan. Her body had been wrapped in a blanket. Investigators determined she had been sexually assaulted, hogtied, stabbed, and strangled. Hammack was a mother of two and was pregnant with her third child when she was killed.

Her case remained unsolved for many years and was one of several cold cases involving women in the Grand Rapids area from that period. Advances in DNA technology and forensic genetic genealogy later produced a profile from evidence collected at the scene that investigators linked to a suspect who had lived in Michigan in the mid-1990s and was working as a long-haul truck driver.

What information might help explain Hammack’s last movements or link her to people she knew in 1996?
