No grips? You're nicked son

There is currently a shrine at the Shell garage up the road from me. Loads of kids laying flowers, hanging around with sad faces. A 12-year-old boy hit a van there and died last Friday. Like the deceased, none of the mourners had any lights on their bikes.
Darwin Awards?

Where is this? Do you have a press reference?

How do you know the boy hit the van rather than the other way around?
