With the death of 18-year-old Pandora Kjolsrud and 17-year-old Evan Clark, three teenagers have been found dead in Arizona's Tonto National Forest since February.

It has been a little over a week since two teenagers were found shot and killed during a camping trip in the Mount Ord area.

For Bill Clark, losing his only son is devastating. He says he will struggle to understand and come to terms with the 17-year-old’s death for the rest of his life.
