U.S. officials say the videos, in their low quality and lack of detail, bear some similarities to those the Taliban released about Bergdahl. They caution that while the videos establish beyond doubt that the couple were captured, they do not qualify as proof of life since there's no mention of current events that could help establish the time.
In addition to calling for government help, the couple in the videos recite names of their family members and certain contact information.
"Just seeing her and seeing her face and hearing her, while it was very difficult, it was also something that relieved a lot of ambiguous anxieties and the fears," said Coleman's mother, Lyn.
Caitlan Coleman refers to her child in the videos, but no child is shown — a fact one U.S. official said was concerning. The grandparents say they don't know the name or gender of the child, who would be about 18 months old.
Even as he holds out hope, James Coleman frets about his daughter's health and a grandchild born into captivity in a foreign country.
"It's an event that just stands out. I think it cries to out to the world, 'This can't be. These people must be let go immediately," said James Coleman.
