The pictures could be priceless. Lost memories.

Or maybe not.

Either way, Todd Rigby wants to find out.

The Salt Lake City man is seeking the owner of an SD memory card his son found on the ground at a hot springs during a family vacation last week in Midway, Utah.

He worries the owner of the digital photos that chronicle a family through an ultrasound, the birth of a baby, proud parents and grandparents, and other activities, might not have downloaded them.

"If it had been my first child in the first two years of their life, I'd give just about anything for it back," he said. "I can only imagine how they feel."

Rigby believes the owner might reside in Coeur d'Alene because a shirt worn by a person in a picture has the words "Coeur d'Alene Lacrosse." There are others that were taken with Lake Coeur d'Alene in the background. They determined the husband's name is Greg from some of the pictures.

He said the pictures cover two years, dating from 2009 to the most recent, April 11, 2011.

He hopes to contact the family and return the card.

"My thought is, maybe somebody knows these people," Rigby said. "If I can get an address, I'd be happy to send them the memory card of their daughter's first two years."

The Rigbys came across the card when a family member stepped on it in Utah. He stuck it in his pocket, brought it home, and this week, pulled it out.

"We ought to look and see what's on that," Todd told his son.

They did.

"That's when I found a few hundred pictures," Todd said.

The card's owner might have downloaded them.

But maybe not.

Todd Rigby suspects that because there are multiple folders on the card for different cameras, "like they moved it from camera to camera," they were not downloaded.

"Some how, it fell out and got lost," he said.

And now, it's found.
