What happened? I don't know! I can make an educated guess:
Motorcyclist with no lights on attempts u-turn and gets rammed by van who could not see him.
These pictures anger me more than anything else. Such an accident is totally preventable. They weren't even wearing helmets. The passenger was alive but I don't know about the driver. I would be surprised if he made it seeing as he is stuffed under the van.
This is why PNP must patrol the roads and enforce safety laws. If they did this then people wouldn't ride around with no lights or no helmets. After passing this disaster scene I saw many more motorcycles and jeepnies and cars with no lights.
Dying or being horribly injured while driving in the Philippines is a (preventable) tragedy waiting to happen.
