A family source says the remains of two adults found earlier this week off the I-15 in the Mohave Desert are those of the McStays. Joseph McStay, his wife Summer and their two young children disappeared from Fallbrook back in 2010.

Clues found in their home led authorities to call the family's disappearance suspicious. Two days after their disappearance their cell phones went dead.

A month later the San Diego sheriff's department released surveillance video showing what is believed to be the couple walking together across the border and into Mexico. A news conference is scheduled for later this morning.
