(CNN)Cynthia Tisdale spent the last years of her life working two jobs to help pay for the medical expenses of her husband, who suffers from a life-threatening lung disease.
The Santa Fe shooting victim worked two jobs to take care of her ill husband. Her death may end up saving his life
Now it appears the death of the beloved substitute teacher in the Santa Fe High School shooting may lead to him getting the medical treatment that could save his life.
Tisdale's husband, William, suffers from idiopathic pulmonary fibrosis, a life-threatening disease that causes scarring in the lungs. It leads to breathing difficulties and a shortage of oxygen in the brain and other organs. And sufferers can only expect a life expectancy of up to five years after diagnosis.
His family set up a GoFundMe page in late March to raise the money for a stem cell treatment. Funds came in slowly at first but soared over the weekend as people learned more about Tisdale and her devotion to her husband.
By Monday morning, the campaign had already exceeded its $30,000 goal -- enough to pay for the stem cell treatment and possibly (with a second opinion) get a lung transplant.
