A family in Michigan is demanding answers from a local dentist's office after April Walters , 46, died in the office parking lot shortly after having her teeth pulled.

Fox 2 reports that despite having sarcoidosis, asthma, COPD high blood pressure and diabetes, her doctor cleared her to have teeth pulled because she was suffering from an infection. Amber Waddell, the woman's doctor, spoke to Fox 2. "I just couldn't understand how she walked out happy and fine and just died all of a sudden," she said.

Waddell added that during the procedure, the medical assistant in the operating room was concerned about Walter's heart rate. "Her heart rate was still 130; the dentist came in, ready to do the procedure," She explained. "The dental assistant said, 'I am waiting for her heart rate to come down.' The dentist said, 'We're fine,' and the procedure starts." The dentist proceeded to pull 16 of the 18 teeth that were set to be extracted before stopping. 

Crystal Cutright, Walters's sister who had taken her to the dentist said the the dentist warned her that her sister should week medical attention. "[She came back] maybe 5 or 10 minutes later and was like, 'Yeah, ma'am, when you leave here you should probably take her to the doctor and get that checked out; her hear rate's kind of high," she recalled.

The situation started to go downhill when they attempted to get Walters into the backseat of their car. Waddell recalled her sister saying, "I can't breath." Waddell assumed her sister's oxygen tank had run out, and when she ran into the dentist's office for help no one was able to administer CPR.

"They didn't do CPR or anything," she said. "They were just rubbing her chest."

An ambulance was called, but by the time it arrived Walters was dead. Now her family is demanding answers as they wait to hear the official cause of death. "A 46-year-old woman should not die in the parking lot of dentist's office," Waddell said.

The dentist's office has announced that they are investigating the incident as well. "We feel deeply for what happened," Caroline Oldsey, the office's human resources rep, said. "Our thoughts go out to them. Our thoughts and prayers are with them."
