An American tourist was arrested in Germany Thursday for allegedly pushing two fellow American tourists down a steep slope – killing one of them – near a famous German castle. 

The incident took place Wednesday afternoon near the Marienbruecke, a bridge over a gorge that offers a view of the Neuschwanstein Castle. 

The 30-year-old man met the two American women, ages 21 and 22, on a hiking path and lured them onto a trail that leads to a viewpoint, police said.

Shocking. Many mentally ill people are walking around freely. It's just bad luck to meet one of them. And like you see with many serial killers. They seem very friendly at first.
