Hi and Welcome!! It would make sense that only one was the target and the rest were just victims of circumstances because they happen to be there. But.............would he really think that one person would be the only person there? He could have easily found out where that one person lived and stalked that person until he caught them alone and then do his nasty deed. Then again, maybe he didn't care how many extra people he had to kill. Like someone said earlier (can't remember who---sorry), if it was a matter of money and book keeping, the books wouldn't change if she were no longer around so whatever it was, would have still been found out.
