The hospital says she's brain-dead. Her parents say she's alive. Who decides when to take her off the ventilator?

A North Texas family is fighting to keep their 9-year-old daughter on a ventilator, though her doctors have said she is brain-dead. But a controversial, unusual Texas law gives doctors and hospitals broad decision-making power. If 9-year-old Payton Summons were lying in a hospital bed in Oklahoma, her parents would have more control over the ventilator that's currently breathing for her. But 100 miles south in Fort Worth, it’s largely left up to her doctors.
