Yeesh, I'm sorry to hear about this. Blast this all over Facebook and other social media places, someone is bound to know the guy and that's a very clear picture of him.
This is just awful. Are there any security cameras outside to see where he went, or perhaps other businesses that have security cameras that show different angles from the street to see what kind of vehicle he went into, back of his outfit, etc?
I would also take a print out of the guy to surrounding businesses and ask them if they have seen they guy. They might have seen him around, know him if he is local or even have him working on their property. If anything, they will know who to keep an eye out for and to let you know if they see him.As others ahve said, unfortunately it seems you have a 'friend' who betrayed your trust in taking these. I would probably say its not any delivery person or other random that told that guy to steal given the description of other valuables he left. So yes, As others said, I wouldnt wait on asking about the cameras outside either. I would be posting it all over your facebook too, if its someone on your contacts list too which I think it might be...
