4 still wanted in Kim Jong-nam case

Investigators are looking for four men from the Democratic People's Republic of Korea who flew out of Malaysia the same day Kim Jong-nam, the DPRK top leader's half brother, apparently was poisoned at an airport in Kuala Lumpur, Malaysian police said Sunday.

Since Kim's death last week, authorities have been trying to piece together details of what happened. Malaysian police have arrested four people carrying IDs from the DPRK, Malaysia, Indonesia and Vietnam.

One of the suspects in custody, an Indonesian woman, told investigators that she was duped into thinking she was part of a comedy show prank.
