"Then we started thinking how in the world are these tapes out because we didn't even know we had lost tapes," Phillip Humphrey said.
The Humphreys figured out they mistakenly left the tapes inside a camera case given to Stephanie's brother-in-law, Kit Applegate, who hardly used the camera and decided to donate it.
"We feel bad for not ever looking in this bag," said Applegate, who recently moved to Sellersburg, Indiana.
With the kids in tow, the Humphreys felt compelled to thank the man who had no gain in finding their family.
One of the tapes featured the family after Stephanie gave birth to their second child. "When we taped it, I remember thinking this is the first time my oldest son is seeing my second son and it's just priceless," she said.
Ultimately, the thrift store find was reunited to the rightful owners.
"I'm sure everyone has their video cameras up in their closet, on their shelves, and they haven't pulled them out for years. So it peaks our curiosity - what's in them? What treasures are in there we've forgotten about?" Phillip said.
