Albert Ogletree was just a name in the 9/11 museum until a worker stepped in

Grant Llera worked to find an old yearbook picture of the man who was working at the World Trade Center when it fell

For years, two tiles showing oak tree leaves stood above the names of two individuals in New York's 9/11 museum's In Memoriam" exhibit whose photos could not be found. The rest of the exhibit features pictures of the 2,977 killed during the terrorist attacks on September 11, 2001.

Now, after more than a decade of searching, a photograph of one of those two victims - a cafeteria worker at the World Trade Center - has finally been located and installed.
