The farm was being rented by a woman in her 50s who was arrested this weekend on suspicion of animal cruelty, said KIRO 7 Eyewitness News reporter Jeff Dubois.

“This is by far the most extreme case that I’ve seen. It was pretty horrific,” Dr. Hannah Evergrenn with Evergreen Holistic Veterinarian said.

A neighbor told KIRO 7 Eyewitness News that the woman moved to the farm last fall and was trying to start a boarding facility for horses.

“I saw the emaciated state of all the horses, I mean they were basically starving to death, the whole head,” Evergreen said.

Members of the group Save a Forgotten Equine said it had been "quite some time" since the horses had eaten.

The surviving horses are severely emaciated and sick, with lice and rot. Two of the rescued horses are in critical condition and might not survive. The horses are being treated at other local farms.

"Anybody that can stand by and you know, eat their dinner and go to bed in a warm be and have horses literally starving and dying right out in front of your property, I just can’t understand that,” Jaime Taft said.
