An investigation is underway after two Arizona women were found shot to death in an overturned vehicle on a dangerous stretch of highway in northern Mexico.
The women, identified only by their last names and ages, were 72 and 82, the attorney general’s office for the state of Sonora said in a release on social media Friday.
The victims, originally from Caborca, Mexico, which is further southeast, were dual citizens of the U.S. and Mexico.
