Keys with blue USB drive and red Milo tag

I found a set of keys this afternoon around 4:15pm in the parking lot behind the Ann Arbor District Library on Fifth Ave, just off Liberty. The ring has a large brass house key, a black car key fob, and a small blue USB drive wedged between them. There’s also a red silicone tag with the name 'Milo' scrawled on it, which should help identify the owner. They’re a little scratched from daily use but otherwise functional. If the owner sees this, I’d be glad to help return them—please reach out.
