I think you're right about these guys.
The island of Aruba is a tourist mecca where lots of young women come for vacation and party time. They were living the high life of women, sex, alcohol and drugs. They were probably used to getting their way, taking advantage perhaps on the woman's last night on the island, maybe even using date rape drugs where the woman doesn't remember what happened. It's all about power and bragging rights for them I suspect.
Something went terribly wrong this time.
Yes there are a lot of other scenarios, but I can't get past this bunch lying over and over and over again. If they are innocent, why are they lying?
Exactly.
If nothing happened, there's nothing to lie about, is there?
