So Karen was attacked because she found out about the "pension" account. She went to Tom? (the legal guy) who was then killed immediately after she met with him before she was able to tell him much according to her story. According to the guy's wife, however, he had found out about something which he had mentioned to the wife before he was killed. There would not be time for him to tell his wife anything according to Karen's story.
Did they find two separate things? Will we get any closure on this whole incident or is it basically just over now? It seems to me that they had both found something unless Karen had met the guy more than once which was not what was implied.
