The family’s disappearance in 2010 sent shockwaves through their community. They were last seen just four months after settling into their new home in Fallbrook, California, leaving behind their two dogs and a puzzling scene with rotting food and untouched finances. The discovery of their abandoned vehicle near the Mexican border raised speculations about a possible relocation, but the truth would later unfold in a grim manner.

Three years after their disappearance, a chilling discovery was made in the Mojave Desert near Victorville, California. A motorcyclist stumbled upon a skull that led investigators to uncover the remains of the McStay family buried in shallow graves. The postmortem examination revealed a horrifying truth – the family had been brutally beaten to death with a sledgehammer, a weapon found amidst the graves.
The investigation took a dramatic turn when Charles “Chase” Merritt, Joseph’s former business partner, was charged with their murders. Prosecutors alleged that Merritt, grappling with financial troubles and a gambling addiction, committed the heinous crime after Joseph McStay decided to end their professional relationship. Merritt was convicted of the killings and was subsequently sentenced to death in 2020, maintaining his innocence throughout the trial.
During the sentencing, Merritt proclaimed his love and respect for Joseph McStay, vehemently denying any involvement in the murders. However, Joseph’s mother, Susan Blake, expressed her disdain, labelling Merritt a “despicable monster” for the unfathomable act of violence that claimed the lives of her son, daughter-in-law, and grandsons. The harrowing saga of the McStay family has captivated audiences and will be further explored in the upcoming ABC ’20/20′ episode.
The case of the McStay family serves as a haunting reminder of the darkness that can lurk beneath seemingly ordinary lives. The intricate web of deceit, betrayal, and violence that unfolded in this tragedy sheds light on the fragility of human relationships and the depths to which greed and desperation can drive individuals. It stands as a testament to the tireless efforts of law enforcement and the pursuit of justice for those whose lives were mercilessly taken.
As the episode delves deeper into the chilling events surrounding the McStay family’s demise, viewers are invited to piece together the intricate details of this captivating true-crime story. The psychological complexity of the case, coupled with the raw emotion and devastating loss suffered by the victims’ loved ones, offers a poignant narrative that will leave a lasting impact on all who bear witness to this compelling tale of betrayal and tragedy.
