Lost small black USB drive with rubber casing and red keychain near Lexington park.

I lost a small black USB drive that has a rubber casing with a red keychain attached. It was last seen while I was walking in the park near Lexington early in the afternoon on October 12th. I'm not sure where exactly it fell, but it contains important family photos and videos that I'd love to have back. It would mean a lot to me if someone finds it.
