When my father’s Android was stolen we called the cops and they told us to the park a block away from the thief’s house (last ping from Find My Device) and wait for them. They took a report from us, confronted the thief at his house, and got the phone back. The thief claimed that he found it at the post office and intended to return it, but the phone was in airplane mode (accessible from the lock screen) so that was clearly never gonna happen. This was in San Jose.
