Was perhaps one of the most surreal assassinations ever:

Exiled brother of a dictator, in an airport surrounded by people and well trained anti-terrorist police forces, killed with a bioweapon, a murderer who thought she was on a Japanese reality TV show, wearing a tshirt saying "LOL" rubbing nerve agent into his eyes and running away with little to no consequence.

She's walking free right now after a small sentence, enjoying life. None of the NK operatives have ever been identified.

I'm dying to know more details -- I did a bit of googling and came up empty. Can you point me to where I could learn more?
