iCloud password compromise and Find my Friends anomaly

I called Support to query about apple ID notification on my iPhone 8 that someone was attempting to use iCloud password in Denver (Showed map of Denver)-I live in Western PA. Not allowing this,I got a follow up notification to change password (which I did).

One thing strange that happened while we were on the phone together was a text msg from a buddy of mine who lives 2 hours north of me in Erie, PA.

We aren’t that social, but, his phone txt me with a map saying “current location”.

I called him and asked where he was and if he sent this strange message. He said he was at his daughter’s address (the pin on the text map), and,”No”, he had not sent a message. I told him I had tried out “Find Friend” with my wife’s phone yesterday. But, had turned it off. He said, he didn't even know about the "Find App.". I called Support back. I was told, this happens all the time. I said this is a statistical coincidence or (insert guess here). Any one want to offer explanation of the two events?
