Dr. Colleen Fitzpatrick tells Dateline’s Keith Morrison about a new tool police are embracing to solve cold cases.
Thirty-eight years ago, an infant boy—hours old, tears frozen on his face—was found dead in a ditch in Sioux Falls, South Dakota. Last week, police arrested his mother and charged her with murder, after investigators uploaded the baby’s DNA to a genealogy website and matched her relatives.
For months, genealogy experts at a firm called Identifinders International examined the DNA of a suspect in a Warwick jogger’s death, learning a lot about his ancestry—but not his name. A big break came when the firm, working with the Warwick Police Department in investigating the 2013 death of a 66-year-old John “Jack” Fay, saw a Buzzfeed News article published Jan. 31.
The mysteries of unknown fate and unexplored lineage weave through the investigations of forensic genealogist Colleen Fitzpatrick, Ph.D. Also an engineer and physicist, she outlines the need for collaboration and data sharing between forensics and genealogy, offers thoughts on future developments, and touches on two historic cold cases.
SANTA CRUZ — When they’re planning to rob a liquor store, most criminals think to wear gloves and cover their faces. But few of them commit to shaving their heads to avoid leaving behind even a single strand of hair.

On the afternoon of Nov. 18, 1987, Jay Cook and Tanya Van Cuylenborg left Saanich, B.C., their hometown, to pick up some furnace equipment in Seattle for Cook’s father.

Their first dilemma was the frozen baby. In January 1988, police in Meriden, Connecticut, discovered the body of an infant in a parking lot. Wrapped in a pink blanket, the blonde, blue-eyed, seven-and-a-half-pound boy reportedly still had his umbilical cord attached.
For more than 25 years, Christy Mirack’s murder was shrouded in mystery — longer than the beloved Pennsylvania schoolteacher was alive. Mirack was found dead in her home just a few days before Christmas 1992, strangled and badly beaten, her clothes askew as if she had been sexually assaulted.
