Yeah some "friend" - Not sure about your situation but that's one reason I stay completely away from Instagram & FB etc. Too may "friends" can find out too much sometimes...
Its always someone who knew about it and knew when to snatch it. Very unlikely someone just happened to grab it by chance. I would use psychological questioning on the people that knew about it and listen to and watch their response.
I kinda know the guy a little bit. I have friends that know him. I never knew anything about him or his stuff. I’m sure it’s someone that know someone that was bragging about it. I don’t say too much about my stuff as I don’t want this to happen to me. Kim
