Which mysteries for the ages have finally been solved?

The McStay family disappearance and murders.

In February of 2010, the McStays, a family of four, seemingly vanished from their home, abruptly.

A carton of eggs was left open on the counter and the family dogs were still outside in the backyard.

The scene was eerie and complicated, because the home

the McStays lived in was in the process of being renovated, so a neat and orderly home wasn't the

norm at this stage. It appeared there was missing furniture and the usual mess that comes with

construction, some freshly painted or redone surfaces mixed with older versions. From the outside, it appeared the family just took off.

Neighbor had surveillance that captured what appeared to be the bottom of the family SUV, leaving the driveway.

Since they were living in California, the border to Mexico wasn't far, and authorities found footage of what appeared to be the McStays walking into Mexico with their two little boys in tow.

The family SUV was found abandoned in a mall parking lot near the Mexico border.

Three years passed before the bodies of the McStays were found buried in shallow graves in the California desert.

The bodies appeared to be in advanced decomposition and there were signs of blunt force trauma.

A sledgehammer was also

found buried with one of the bodies. Chase Merritt, a business partner to Joseph McStay, was arrested

and charged with their murders in November 11, 2014. His trial was delayed for years until 2019. He

was sentenced to death. Motive? Chase had a gambling addiction and had been and continued embezzling money from the business.

His DNA was found in the McStay's abandoned vehicle.

He bludgeoned his business partner and their family to death for money.
