Here is the
Application and Affidavit For Search Warrant.

On page 11 it starts to get interesting. Look for the "Facts In Support of Affidavit" section.
They are accusing this guy of ripping off AT&T and Verizon, Pirating software, SPAM, illegally upgrading his router software (wtf?), carrying an unlicensed firearm, having a large amount of data being uploaded through his home Internet which they assume means he was, "dealing in pirated software and movies, operating SPAM servers, or remotely administrating computer networks."
Then it talks about many forum posts he may have made under the name CygonX where he bragged about being a "lifetime pirate and gamer" among other things... He also is accused of being an administrator for UWWWB.com.
