Sorry, that didn't really come out like I thought it would. It's a terrible thing that it would happen, but I also don't understand what would make someone kill for so little? Do they see the value of human life so low?
And the old people and kids reference was to The Man Who Knew Too Little, about a bumbling man who thinks he's on a TV show and is accidently an outrageously successful spy in the process.
In seriousness, it's really an unbelievable tragedy, but I had assumed that there was a personal vendetta or jealousy or some other reason besides just wanting money for which they would kill such a person.
Sorry,
Daniel
