I had forgotten about Pound Ridge! This is where Dulos built the million dollar pavilion for his in-laws, yes? Which means he's INTIMATELY familiar with the topography there. Water sheds, culverts, potential abandoned wells or other naturally occurring formations. Septic mounds, possible previous or failed septics....
My speculation only, but FD strikes me as just the sort of person who could borrow $10 from you and then get OUTRAGED that you should ask for it back.
Methinks that, despite the senior Farbers extraordinary generosity, FD was simmering underneath, resentful of their wealth, resentful of anything that appeared to him like them trying to control him with money (even while he was trying to CONTROL THEIR DAUGHTER)... I wonder whether he SEETHED while doing work for them. Again, he strikes me as someone who just always has OPPOSITE emotions, compared to normal people. Instead of gratitude, resentment. Instead of contentment, greed....
I want to go on record here: the ultimate "in your face", Pound Ridge is my #1 guess for leaving JF's remains. A place he could access with some sort of ease, within the radius of opportunity, AND a grotesque win for him, disposing of their daughter in their own backyard. A sick mind would delight in that.
I am certain he had been plotting this crime, probably in any number of configurations, for YEARS, probably ever since Jennifer left him, cutting off his access to the money he'd grown to love. I bet further he sees the world very differently than the rest of us. Revenge being his lifeblood. He likely saw the lay of any land as perfect places to get rid of a body, which is why I'm convinced he was able to do what he did with such horrifying efficiency. Question is, are there cameras between Welles and Mallard?
I believe he took her exactly where he planned to take her.
