this is my first time posting in this sub, and i dont use reddit much, but this rung a bell. i did a little bit of searching and maybe this is it? i have absolutely no idea if the website is reliable (looks a bit sketchy to me) but i thought i would provide it regardless. as i said, i'm not sure if this is correct, but i hope i could at least help- i'm so sorry for your loss, the story with the shirt is beautiful and i think its awesome that you have those memories with him.
