<human>: article: 

Right after graduating high school, a friend and I went to Austin to visit a friend. She showed us around town and took us to a few of her friend's houses. At one house in particular we weren't treated very kindly. Once we arrived all the people in the house moved to the kitchen and avoided us for the most part. We left shortly after. A day or two later in the hotel room the news was on and I half-mindedly listened to the report of two people being murdered in west campus. All I remember thinking was how I thought Austin was supposed to be a peaceful place. When it was time to go back home my friend told us she would take us a back way and we met up at the same house where we were treated rudely. For the most part it was the same people that were there the first night we went, including the two guys that (unbeknownst to me at the time) committed those murders I just so happened to learn about vaguely on the television. I saw these people before and after they killed two people and you couldn't even notice a difference in their demeanor. My friend called me a few months later to tell me the whole story. What's the weirdest thing you experienced without knowing it but ending up finding out about later?

Can you give me the gist of the text in a nutshell?
<bot>: Went to visit a friend in Austin. She took us around to a few friends houses. Met some of her friends who, in a few days, would end up killing a young couple in Austin.
