7 suspects are at large, 4 of them, all North Korean, left the country on the day of the attack.

Four others are already in custody including a North Korean chemistry expert and both alleged female attackers.

The women told investigators they thought they were pulling a prank for a hidden camera TV show.

Malaysian police say they’ll wait one more week for a next of kin to come forward and claim Kim’s body, though North Korea has already requested it.

As for the suspects in custody, they’ll appear in court Wednesday to either be charged or released.
