6-inch Star Wars action figure in blister pack

I found a mint-condition Star Wars action figure this afternoon around 3:30 pm behind the Cedar Falls Public Library on Main Street. It's about 6 inches tall and still sealed in its original blister pack; the card back has a little corner wear and a faint crease along the top edge. The packaging is mostly black and red with the Hasbro logo visible, and the figure inside wears a dark jumpsuit with a blue cape—I can't tell the exact character without opening it. There's a small pencil initials CF sticker on the back of the card, which could help identify the owner, and I'd love to reunite it with them.
