To me he sounds like he is ordering them down the hill, I didn't take it as casual at all and I did think it sounded like his voice had an edge to it, like rudeness or confrontational...so I guess that is for each of us to decide too. I listened to it over and over to see if I could at least pick up an accent or something to see if he sounded like locals there or people from a location I am familiar with. Listening to it gave me the creeps, but maybe only because I know the girls were murdered after that.
