If they weren't bluffing and you're in the same county, it could just be the dispatcher remembered you from last time. I had something analogous to this where the local PD left a voicemail saying my brother had gone missing and left a name with the same last name and a name similar to mine. When I called back, I told the dispatcher and they refused to leave it there and wanted to transfer me to the cop in question which I thought was really weird. He took it down but it seemed like there was something else there. And I realized he was probably fishing to serve an arrest warrant or something. To see if I would go, "No, my brother isn't missing. That's my cousin and he's at <address>." Cops do that type of shit all the time.
