According to the Chicago Tribune, Arellano said of the 44,000 pirated movies found in his home, "my mother saved all of the DVDs, CDs and videos...She saves those." His mom is also selling the stolen movies on a French website, I guess, since his computer turned up a link to such a site during the investigation.
His kids are big fans of Hannah Montana, too. Maybe they were in on it.
On the other hand, at least he didn't wish on Miley/Hannah various venereal diseases and drug habits as per class act Jamie Foxx.
