Looks like it's one of the many native species: http://www.virginiaherpetologicalsociety.com/reptiles/turtles/turtles_of_virginia.htm#_I'm in northern Virginia. Box turtles are native here, but he doesn't have a hinged shell like I'm used to seeing in box turtles.
Good! Countless numbers in future generations are lost with each animal removed from the wild breeding population. I'm so glad this boxie's gone home.I released him close to where I was told he was found, which was pretty close to the vet clinic I work at.
