Every year, on the anniversary of the September 11th attacks, Elizabeth Stringer Keefe has posted online the same wedding photo a friend found at Ground Zero, in the hopes that she could reunite the photo with its owner. She tried again this week:

Every year on #911 I post this photo hoping 2 return 2 owner. Found at #groundzero #WTC in 2001. Pls RT pic.twitter.com/mZ9LdQqE7x

The photo got lots of attention online, and was retweeted by lots of people, including celebrities like William Shatner and Blake Shelton. And then, just last night, a breakthrough:

@ProfKeefe I KNOW THE PEOPLE IN THE PICTURE! I was at the wedding.

Keefe and Mahe connected, and she managed to speak with him directly:
