"Hello, Dad?"
"Yes, Bethy. Are you ok?... When can you come home?"
"I don’t know."
Those were a few of the words eight-year-old Beth Stauffer managed to exchange with her dad during an FBI- tapped phone call on Father's Day in 1980.
Beth and her 36-year-old mother Mary, a former high school teacher, had been missing for weeks after being kidnapped.
Their abductor allowed them to make a phone call home after he forced them into his car at gunpoint when leaving a hair salon weeks earlier on Friday May 16, 1980.
That day, the daughter and mother-of-two had decided to get haircuts before their family would fly overseas for a missionary trip to the Philippines in a few days' time.
After making their way back to their car, the man approached them and held a gun to Beth's side.
At the time, Mary had no idea who he was or what he wanted with them - only that he demanded they get into his car.
"The reality was, there was no place for me to understand what was really happening at the time of the abduction," Mary later told People.
"I knew I was scared, and I know she was scared and I knew he was angry. That’s really what I knew at that moment."
Mary would later learn the man behind the gun was someone she knew 15 years ago. He was her former student she taught in a ninth-grade math class at a Minnesota high school - Ming Sen Shiue.
