To your list of suspicions, I would add: isn’t it convenient that the female interest is conveniently out of the country?
Was this part of the plan to avert attention from her being complicit?
Time will tell.
I think the female lady came to realize he was broke. Whatever fortune that he had...no longer existed.
They’ve already said that she’s no longer a person of interest.
Then again they initially ruled out the Pulse killer’s wife as a person of interest.
