A Monmouth, OR woman's life is in serious danger after being struck with a mysterious illness that Portland doctors are still trying to diagnosis. Since first becoming ill on Thanksgiving, 18 year old Tabitha Schulke has had the lower half of her legs amputated and is currently in critical condition.

Doctors believe that the teen developed gangrene in her feet which caused doctors to amputate part of her legs to keep the disease from spreading. Test results are being conducted and the belief is Tabitha is suffering from toxic shock syndrome caused by a staph infection.What initially caused that illness is still unknown.

Dr. Eric Chang with Legacy Emanuel Hospital in Portland told KATU News:

When she came here, she was very close to death and she's come very far, so that makes us very hopeful for the future.
