& # 39; My original opinion was wrong, and the new information and data showed that the information was indeed present. & # 39;

Cook and Van Cuylenborg were said to be random targets.

All potential leads in the double homicide case had long been absent until the DNA evidence of the 32-year-old crime scene was placed in a public genealogy database named GEDmatch.

The database, checked by a company called Parabon NanoLabs, consisted of DNA samples from 100 crime scenes and was able to find matches with people determined to have family ties with potential suspects.

& # 39; The significant races were roughly at the level of the second cousin, & # 39; Paralo genealogist CeCe Moore said to reporters at a press conference after Talbott & # 39; s arrest.

Moore had to establish a family home of the great-grandparents of people whose DNA profiles matched evidence found at the crime scene.
