Mahe himself says:
It is my picture that was at my desk on the 77th Fl of WTC Tower 2.The picture has been kept safe by @ProfKeefe 4 last 13yrs
In 2001, a friend of Elizabeth Stringer Keefe, a professor at Lesley University, found this photo at Ground Zero and passed it on to her. Ever since, Keefe has been trying to find out who the people are, so she can return it to them - or their relatives.
