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.

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.

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.
