"Very painful, very painful, I was sprayed liquid."
Those were the last words of Kim Jong Nam, half brother to North Korea's leader, Kim Jong Un, as he stumbled through a Malaysian airport.
In a busy departure terminal on Feb. 13, Nam wandered about 50 feet before finding an airport receptionist, to whom he spoke his final words, according to Asia One. He was quickly helped to the airport clinic, where he fell unconscious.
Nam was rushed to the hospital, where was pronounced dead upon arrival. Authorities suspect poisoning.

At least three women and one man have been arrested in connection with Nam's death. On Feb. 14, the first two women were arrested, separately, under suspicion of having sprayed liquid in Nam's face before fleeing the airport in taxis.
Indonesia's national police chief, Tito Karnavian, told reporters on Feb. 17 that the two suspects were paid to participate in a hidden camera "comedy prank show," CBS News reports. The "pranks" were to involve the women convincing men to close their eyes and then doing surprising tricks, like spraying them in the face with water.
"Such an action was done three or four times, and they were given a few dollars for it," Karnavian explained. "And with the last target, Kim Jong Nam, allegedly there were dangerous materials in the sprayer."
"She was not aware that it was an assassination attempt by alleged foreign agents," Karnavian added.

The autopsy, which may reveal Nam's official cause of death, was finished on Feb. 17 but has yet to be released to the public by Malaysian officials. According to The Telegraph, the unreleased report identifies the poison used on Nam.
Nam was in his mid-to-late 40s and led a private life. He had multiple children during several different marriages and traveled across the globe.
Nam was born from a secret love affair between his father and an actress, leading to a life of secrecy and separation from his family in North Korea.
