The 30 Second Mystery 66 - Why?

[Peetster]

There are four categories: Who, What, Where and Why. Some will be easy, some not. I have as many as six clues to help you along, which I'll supply as needed.

Please limit yourself to one guess, and another guess for each clue I supply. No questions asking for help or hints are allowed. Partially correct answers won't be acknowledged.

Wild guesses and comments are fine. In fact, they can add to the mystery and are fun to read. Be precise when guessing.

Be patient.

The Case:
In addition to pictures of his wife and children, Jack carries pictures of some people that have passed away. Jack admires the people, but they are not related.

The Mystery:
Why does Jack carry these pictures with him?
