Though his father’s DNA partially matched that of the killer’s DNA, this innocent suspect’s DNA did not produce a match. After over a month in a jail cell, investigators finally determine that the suspect is not the killer. The police make an arrest, only this time they have arrested the wrong person. They find a partial match, obtain a court order requiring the database to reveal the identity of the partial match, and then investigate that person’s relatives as potential suspects. As a last-ditch effort, investigators run the genetic profile through a third-party database primarily used for genealogical research. DNA evidence of the suspected killer obtained from the crime scene produces no results when run through existing government databases. A rapist murderer evades police detection for years.
They arrest the serial killer after over thirty years of searching. After analyzing a DNA sample obtained from an object the suspect has discarded, investigators confirm an exact match to the crime scene sample. Investigators follow-up on this lead, determine the identity of the relative, and, using standard investigative techniques, uncover the identity of the suspected killer. The search does produce a partial match, indicating that one of the profiles in the third-party database is genetically related to the killer. Investigators, in a last-ditch effort, run the suspected killer’s genetic profile from the crime scene DNA sample through the third-party company’s DNA database, hoping to find at least a partial match. But years after the crimes have been committed and the leads have all dried up, one of the killer’s relatives submits a sample of her DNA to a third-party DNA database to research her genealogy. DNA evidence of the suspect obtained at a crime scene produces no viable leads when searched through existing government databases.
Investigators fail to find him, and he seemingly disappears for decades. Killer’s Code – Familial DNA Searches Through Third-Party Databases under CarpenterĪ man terrorizes an entire state for years, raping and murdering innocent victims in the dead of night.
