I confess, I made a mistake about the hand grenades, they used C4. The case has been getting news here since 2006, there have been many accusations that the Deputy Prime Minister's wife has been openly connected to the crime, although not charged. This isthe way in Malaysia.
From a Wiki article
here if you want more interesting reading on this case have a troll using "Murder of Shaariibuugiin Altantuyaa" as your search.
Shaariibuugiin Altantuyaa (Mongolian language: Шаарийбуугийн Алтантуяа; sometimes also Altantuya Shaariibuu; 1978 – October 18, 2006), a Mongolian national, was a murder victim who was either murdered by C-4 explosives or was somehow killed first and her remains destroyed with C-4 on October 18, 2006 in a deserted area in Shah Alam, Malaysia near Kuala Lumpur. The Shah Alam High Court meted out the death sentence to two of the accused on 9 April 2009, wrapping up the 159 day trial.
