Bodies of Missing McStay Family Found In Calif. Desert

California sheriffs say they've found four bodies they believe to be the McStay family. The McStays disappeared more than three years ago.

Since 2010, the search for the missing McStay family of California has drawn international attention and puzzled investigators. Police now say they might have found all four of the family's bodies.

That’s Michael McStay, the brother of Joseph McStay — who, with his wife and their two sons, went missing in 2010 when they were living in San Diego County.

For more than three years, investigators have speculated that the family packed up its belongings and left the country. The family's SUV was found two blocks from the border four days after they went missing. (Via KCAL)Some even thought they saw the McStays in a surveillance video taken at the Mexico-U.S. border. Several investigators scoured the globe thinking the moderately wealthy family had voluntarily disappeared. (Via Fox News)

But the case is largely still a mystery. San Bernardino County Sheriff John McMahon wouldn't give any details about how the family might have died. Authorities say they are now treating the family's deaths as a homicide investigation.
