SAN DIEGO (CBS 8) - Prior to Friday's official announcement of the discovery of Joseph and Summer McStay's remains and the discovery of the presumed remains of their children, Joseph's father Patrick McStay spoke with CBS News 8.
"In my heart, I knew it was coming," Patrick McStay said.
Just hours after learning some of the skeletal remains found just outside Victorville are that of his son Joseph and daughter-in-law Summer, Patrick McStay struggled to answer one question: just what happened?
"I have my suspicions why and I have my suspicions who. There's no answer for that," he said.
The remains were discovered in two shallow graves at the Mojave Desert location less than 150 miles north of San Diego. Deputies with the San Bernardino Sheriff's Office were called to the area on Monday after a motorcyclist traveling off-road saw what he thought were human bones.
According to Patrick, an official with the department later visited another family member and confirmed they had identified Joseph and Summer, but were still waiting to figure out if the other remains were those of their two young children Gianni and Joseph Jr.
"Why Victorville, I have no idea," Patrick McStay said.
Joseph McStay, his wife Summer and their two young sons vanished from their Fallbrook home in February 2010. Their disappearance captured headlines here in San Diego. The last time was back in April of this year, when the sheriff's office turned the case over to the FBI, saying surveillance video showed the family entering into Mexico willingly.
"The FBI does have significant investigative assets in other countries and a lot more experience dealing with investigations in other countries," a sheriff's department spokesman said.
Meanwhile, Patrick says he always suspected foul play.
"To me, everybody is a suspect until we find out who did it," he said.
The McStays' car was found a couple of blocks away from the Mexican border. Patrick McStay says his son would never have disappeared on his own.
