This episode covers the cold case murder of Robin War Lawrence, solved after nearly 30 years through DNA advancements and genetic genealogy. Key discussions include the brutal details of Robin's murder, the investigation led by Fairfax County detectives, and the eventual confession of suspect Steven Smirk.
Robin Lawrence was murdered in her home in Springfield, Virginia, on November 18, 1994. Her husband, Olly, was away on a business trip when Robin was found stabbed 49 times. The episode features insights from detectives Melissa Wallace and John Long, who revisited the case in 2021.
Detectives discovered a bloodied washcloth at the crime scene, which became crucial evidence. After years of stalled progress, genetic genealogy expert Liz took on the case pro bono, eventually identifying Smirk as a suspect through extensive family tree research.
In September 2023, Smirk turned himself in, claiming he was a serial killer who had only killed once. His confession revealed disturbing details about the murder, including that he had no prior connection to Robin.
The episode concludes with the family's mixed feelings about the resolution, as Smirk accepted a plea deal for first-degree murder, receiving a 70-year sentence with the possibility of parole.
