Oh, no, not KASHMINA! Oh, hell's teeth. She was owned by Heart of the South Racing, a very enthusiastic group who will feel her loss most keenly. I think it fair to say that some will have been in tears. She was one of Sheena's better horses and always a trier. I'm really saddened to learn this - the group had been doing very well, and this was one of their little stars. Okay, at a low level, but she was much loved.
I've had a look at the RP, and it just says PU after the 2nd hurdle, lame. Obviously something went horribly wrong.
