Sorry man, thatβs freaky. Dude sounds unhinged. What info do you have on him from Facebook? The info he says he has on you - how much did he actually prove by stating it? Could be that he just got the minimum info and is making the most of it to make it sound like he knows a lot more.
When you spoke to him, what kind of accent did he have? Did he sound local?
Can I ask how you know it was him calling your wife? How were you guys able to block his number without being able to view it?
