According to the news I read today, the suspected woman was arrested by Malaysian police. She confested to have carried out the murder of Kim Jong Nam. She traveled with another woman and four men. The men told them (the two women) to spray on Kim's face and cover his face with a piece of cloth. After success, they all leaved the airport and meet a hotel somewhere 55km from the airport. A day later, the men went out and never come back. She went to the airport to find her friend because she didn't know the language and not familiar with the traffic there. She was arrested at the airport.
