A new documentary series hosted by CrimeOnline’s Nancy Grace and presented by the same producers of “Unsolved Mysteries” and “Forensic Files,” will give viewers a behind-the-scenes look at murder investigations in a never-before-seen way.

“Bloodline Detectives” takes viewers on a fascinating 12-series journey as investigators help solve cold cases with the help of Familial DNA Search technology. The innovative technology helps authorities by pinpointing the criminal’s family members through familial DNA. A genealogy database then helps trace the family tree to reveal the true killer.

Grace, a renowned legal analyst, and host of “Crime Stories with Nancy Grace,” will lend her voice and opinions to detail each case, which includes some of the nation’s most high-profile murderers, including those who’ve been caught via Familial DNA Search.

Familial DNA Search played an integral part in catching murderers such as The Golden State Killer, Joseph James DeAngelo Jr., a former cop responsible for a slew of rapes and deaths during the 1970s and 1980s.

“Forensic technology is changing the way criminal investigations are conducted,” Grace said. “No doubt familial DNA will help solve cases that have remained open for decades, like those presented in ‘Bloodline Detectives,’ and will contribute to a sense of healing for victims and their families.”

Each episode will also provide key witness testimony, archival footage, crime scene reconstruction, and expert interviews from forensic and psychological experts.

“Fascination with crime has been around since the beginning of time; we still talk about Cain and Abel – the first murder, that we know of. In fact, our founding fathers stated in their equivalent of legislative minutes that they wanted courtrooms to be big enough for the whole community to see justice unfold,” Grace told Deadline.

“Bloodline Detectives,” will premiere on October 3. Check your local listings for station information and start times. The show will appear on streaming platforms in 2021.
