Walters had the teeth pulled despite the fact that she was feeling anxious, her family said. She was battling a series of health issues, including diabetes, high blood pressure and asthma, and was reliant on an oxygen machine.
"Her heart rate was still 130, the dentist came in, ready to do the procedure," Waddell told the station. "The dental assistant said 'I am waiting for her heart rate to come down.' The dentist said 'We're fine' and the procedure starts."
After Dr. Rana Rabban was done, she told Walters that she should "go to the doctor and get your heart checked on," Waddell said.
Shortly after April's family got her and the oxygen tanks into the car, she started having trouble breathing. It was thought that the oxygen tanks had run out, so they got more oxygen from the dentist's office.
That didn't seem to work, and Waddell said that no one from the office knew CPR.
