Maybe it's because of how the article was worded, but I'm having trouble comprehending how he was able to "participate" in the forced sexual acts between the people he assaults/kidnapps. It seems he targets couples and forces them to start performing and then joined in. Did he keep his rifle on them both the entire time or tie them up? I'm not asking for details, and I'm not saying that the previous victims were cowards or anything like that, I just don't understand the logistics, I guess.
It's odd.
