According to public documents the case has additional defendants(highlighting ours):
Court Case Number: 2:11-cv-06310-ODW -SS
File Date: Monday, August 01, 2011
Plaintiff: Summit Entertainment LLC
Plaintiff Counsel: Dennis L. Wilson, David K. Caplan, Christopher T. Varas of Keats McFarland & Wilson LLP
Defendant: Daiana Santia, Hector Santia, John Does
Cause: 17:501 Copyright Infringement
Court: California Central District Court
Judge: Judge Otis D. Wright, II
Referred To: Magistrate Judge Suzanne H. Segal for discovery
Hector Santia has not currently been cited in the Summit press release as to what his suspected involvement is. In the Eclipse case, part of what initially happened was that the person to whom the Internet service was registered was initially served until it could be established specifically which person with access to that Internet service had actually done the hacking and had actual knowledge of illegal events.
Also interesting is the listing of John Doe defendants. This too happened in the Eclipse case. Initially, the online aliases of of illegal image distributors were listed along with John Does. In other words indicating that perhaps there were others who assisted in the hacking whose specific identities were not known at the time of the filing. However, when those individuals were identified months after they too were then named in the case.
The final interesting piece is that Judge Otis D. Wright, II is the same judge who presided over the Jordan Scott vs. Stephenie Meyer case. In that case, which was ended in the favor of Stephenie Meyer, Scott claimed that Stephenie Meyer had based Breaking Dawn on her novel The Nocturne.
