Someone used "Find my Iphone" to wipe my phone. Can I use the same app to find their location?
No, The app doesn't expose past actions and events to users.

You should check that your AppleID is emailing an email address you control since erase and lock events trigger an email to the email on record for admin changes / security at https://appleid.apple.com

There might be server logs and if you are really interested in knowing who erased your phone, having your lawyer contact Apple legal promptly would be the best avenue to get cooperation to track down where/who may have compromised your account. That would both help you decide to press charges and certainly alert Apple to the situation in an official and formal manner.

Of course, you should change your AppleID password immediately to some password you don't use on any other online site. Consider enabling two factor authentication as well if you wish to make your account harder to hack into going forward.
