Walther also allegedly admitted that 'he would download child pornography files, but would often feel guilty and go through a ‘purging’ of files, i.e., deleting the images and associated files, because he knew it was wrong,' adding that he had last deleted such files Nov.

When investigators searched Walther's residence after they obtained federal search warrants, he allegedly admitted, among other things, 'that he had a pornography addiction and would often go through cycles of downloading and viewing pornography depicting both adults and minors' but said he did not know he was sharing the child sex abuse files on the peer-to-peer network, according to the criminal complaint.
