Down the pipe

Jessica decided the covered pipeways would be sufficient cover. At worst, she could likely find a hidden place to wait the night out. Limping, Jessica went over to check out the pipe.
"CRAWK!". a sudden noise, behind Jessica, as a dog sized crow fluttered down from an unseen rafter overhead. Far too close, its yellow eyes reflecting little more than hunger as it shuffled her way. Jessica was in no shape to face the thing, but she also had some space from it, so she redoubled her pace, and hurriedly entered the dark of the pipe tunnel.
The interior was no brighter, and she had to trace a hand against the wall to orient herself. She was no further than 20 paces, when she heard a strange splashing. Jessica froze. Then an enormous roar that Jessica could feel in the very walls, as some large beast rushed toward her. Scared and confused Jessica braced herself. But it did little to save her against the thousand pound porcine trampled her.

No particular moral or failing here, sometimes you walk into a trap. That doesn't want to fuck.
