Did the wife kill Thompson?

[mathematic]

23. There was an investor meeting and 6:45am is pretty busy in midtown

His whereabouts were public known.

He was not staying at the hilton, the conference was at the hilton. He was staying at the hotel across the street. This is in the news reports your brother should have gotten his information from.

I think it's very strange that you use utterly mundane facts about this event, like an executive being at an investor conference at the start of the business day in midtown manhattan as evidence for any theory.
