A UC Santa Barbara student and Nexus university news editor has been reported missing in Baja California after going on backpacking trip with her family.
Maura Fox, 20, left for the trip on June 20 with her dad, Morgan Fox, 61, and her sister, Claire Fox, 25.
The family was expected back on Saturday, but Mexican authorities found their car parked by the mountains on Sunday, according to NBC San Diego.
Relatives said the family had hiked in the same area of Baja California before, but they have not heard from the group since last Tuesday when they left for the trip.
