I don't know what happened there, but some things in cookiengineers posts does not add up. There is no "BKA Heidelberg". The BKA has three offices in Germany, and Heidelberg is not one of them. Also, the BKA will likely not investigate in such a matter. It is doing large scale investigations crossing federal borders, like organized crime or terrorism. It is not working on local crime cases on the described scale. This is done by "normal" local police.
