According to Texas law, a person is considered dead if he or she suffers an irreversible loss of all brain function. Cook Children’s attempted to find another hospital to take over Payton’s care, but so far every facility has agreed with doctors’ statements that nothing more can be done for her. Family members told NBC5 that they are still reaching out to medical organizations to see if any will accept Payton’s continued care. The hospital said the girl’s cardiac arrest was caused by a large tumor in her chest that shut off her circulatory system. She survived cancer as a toddler, and her father, Joseph Summons, said he believes “a miracle will happen for my daughter,” WFAA-TV (Channel 8) reported. Staff writers Claire Z. Cardona and Dana Branham contributed to this report.
