I found this earlier this afternoon around 2:15pm in the parking lot behind Safeway on S. 7th Street in Sierra Vista. It's a black 2.5-inch Samsung external SSD, about the size of a paperback, with a matte finish and a small scratch near the USB-C port. There's an engraving on the corner that reads 'J.R.' and a blue LED indicator that glows when plugged in. It looks like it held important files, and I figured the owner would want it back. If this is yours, we can arrange a quick meetup near the library or the coffee shop on 7th Street to get it returned.
