Could this FA have been DS's lover? Note the quote:

When his tirade was through, he then took a some beers from the galley and pulled the emergency chute and slid off the Embraer 190 plane. According to police sources, he threw his luggage down first and said something to the effect of "there goes 28 years," before he took the plunge.

28 years? The same time that DS was at OH! Coincidence?
