She's at Lancaster Animal Control (Los Angeles, CA), and is listed as a 3-year-old mare named "Camilla." Nothing else is known about her.
Here is the listing -http://animalcare.lacounty.gov/wps/portal/acc/our_animals/detail?animalID=A4662399&page=1
We would be happy to help any rescues interested in this mare, and can try to stop by Monday morning to take a look at her in person. Til then, website info is all we can go by.
