What's wrong with people

The big news in Japan today is that some guy kidnapped a 17 year old girl/woman and kept her in his house for 3 weeks (handcuffed). Apparently they met on a mobile phone dating service. Interestingly, he lived with his mother and brother... who apparently didn't notice anything suspicious?? Yeah, right. I hope they get charged to. This is right on the heels of some other guy who kidnapped a 19 year old woman last week - he kept her hostage for several weeks as well.
