1. Jealousy: coz Jibby must have cried out her name too many times in his sleep. Ok, Ok, just couldn’t help myself. She knew of their affair.

2. Extreme Hatred: She need to see Altantuya dead to the extend of wanting to witness the complete destruction of her physical body. Could have been a suggestion by her aide-de-camp (she knows what plastic explosive can do) to pacify her boss’s intense dislike for the Mongolian Beauty.

3. Pregnancy: She knows Altantuya is pregnant with Jibby’s child. The idea of another woman bearing ‘his’ child and the inevitability of birth is unbearable and totally ‘heinous’ in her eyes. Mother and child must perish in the most gruesome manner to warrant justification of her mental torture.

One thing is for certain. RPK definitely have in his possession some very convincing evidence. Could just hear the whistle blowing downstairs.
