How can I return a lost iPhone?

Episode 1171 (29:51)

Pete from Brooklyn, NY
iPhone 6

Pete found an iPhone on the road and it's locked. How can he track down the owner and get it back to them? Leo says that there really isn't much he can do other than file a 'found phone' report. He could interact with Siri and see if he can get information from her. In fact, he can use Siri to return it, according to 9to5Mac. But if Siri has been disabled, there really isn't a lot he can do. He could also contact Apple. Maybe they can help. But outside of that, not much else can be done, especially if a kill switch has been deployed.
