Man burned alive in his house due to sudden fire - in the middle of the night.

And yes, this man is none other than one of my relatives in Malaysia. It is saddening, because I still remembered visiting that same house years back. He still looked healthy and alive then... But its really heartbreaking to hear about why and how he died. This made headlines in Malaysia.
It must had really been a painful process to be BURNED ALIVE, and worse still... all his identification and documents vanished in the fire, and he was classified as anonymous by the police until my relatives went to claim his body. (Yes, his body was burned until beyond recognition...)
The house which my family had been to before is now in a disastrous state. As you can see from the picture above (taken from one of the Malaysia news site), the roof was in a bad state,too.
Why...? Why... ? Why... ?
