My friend owns a PC cafe and today, about 6 guys came in and stole 11 of the computers and in the process, stabbed another one of my friends and tied up one of the customers. My friends ok though and the customer didn't get hurt. But I would really like to be able to track down those computers and especially find those assholes. So, here is what I want to do. If I have the mac addresses of the nics, is it possible to find any information about where those computers would be physically located? I once read that a guy got his notebook back by doing that but I don't know how he did it. If anyone can provide me with some insight, that'd be great. Thanks.
