Wasn't wearing a helmet and her boyfriend lost control of the bike. They plowed into the railing of the bridge they were on and she struck her head, shattering her skull and tearing off most of her scalp. Then she bounced back several feet and expired in the middle of the road. Boyfriend survived.

She probably would have too, if she'd had a helmet on. But instead she's on her way to the gore forums, with a head that looks like a canoe and some very pissy pants.
