Season Two of Only Murders on the Harbor opens with one of the most disturbing cases to emerge from Grays Harbor County, Washington. This episode examines the life and violence of David Allen Gerard — and the victims whose stories might otherwise have been forgotten.
Raised in Aberdeen, Gerard’s early life was marked by instability, isolation, and escalating aggression. Over time, his relationships became increasingly volatile, with a documented history of domestic violence that, in hindsight, revealed a much darker pattern.
Throughout the 1980s, several young women disappeared or were found murdered across rural western Washington, including Carin Connor, Connie Rolls, Roberta Strasbaugh, and Tracy West. While none of these cases have been definitively linked to Gerard, similarities in victim profiles, locations, and circumstances continue to raise questions.
The episode centers on two of the most brutal killings: Elaine “Brooke” McCollum in 1991 and Carol Leighton in 1996. Both women were last seen in Aberdeen before being found along the same remote logging road. Each case involved extreme, rage-driven violence, and despite extensive investigations, both went cold for years.
Everything changed in 1999.
After surviving a near-fatal claw hammer attack in a dairy barn, Frankie Cochran identified Gerard as her attacker. Her survival became the turning point investigators needed. At the scene, Detective Lane Youmans recognized a chilling similarity between the attack and the earlier murders — a realization that led him to reopen the cold cases.
As forensic technology advanced, DNA evidence linked Gerard to both McCollum and Leighton. Yet legal barriers complicated efforts to fully prosecute him. Gerard ultimately entered an Alford plea in Leighton’s murder and is serving time for the attempted murder of Cochran, but questions remain — particularly in McCollum’s case and others that may be connected.
The episode also explores the suspicious 1995 house fire that killed Gerard’s former girlfriend Patty Rodriguez, her two sons, and her mother — a tragedy ruled accidental, but one that continues to raise doubts.
At its core, this episode is about persistence and memory — the work of a detective who refused to let these cases fade, and the lives of the victims who deserve to be remembered.
In Grays Harbor, the past never truly disappears.
