She went to the dentist to have her teeth pulled but passed away shortly after the procedure and now her grieving family wants answers.
"I just couldn't understand how she walked out happy and fine and just died all of a sudden," said Amber Waddell.
Waddell and her family want answers. They say that Friday her mother left home for a dental procedure - and never came back.
April Walters suffered from sarcoidosis, asthma, COPD high blood pressure, diabetes and she was on oxygen. Walters, 46, wasn't in good health but she had been cleared by her doctor to have her teeth pulled because of an infection.
Her sister, Crystal Cutright, took her to Dr. Rana Rabban at Southfield Dental Care Friday at 10 a.m. but the medical assistant who took her vital signs seemed concerned.
"Her heart rate was still 130, the dentist came in, ready to do the procedure," Waddell said. "The dental assistant said 'I am waiting for her heart rate to come down.' The dentist said 'We're fine' and the procedure starts."
April had anxiety and was nervous. She had been turned away before because of an elevated heart rate - but not this time.
After 16 of 18 teeth had been pulled, the dentist told her they would stop for the day.
"She was talking to April she said 'I think you need to go to the doctor and get your heart checked on,'" Waddell said.
Crystal says the dentist left to see another patient, but came back.
"Maybe five 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 heart rate's kind of high.'"
Crystal was starting to worry, trying to get her sister and her oxygen tanks to the car. Her husband James helped get April into the backseat, but then - trouble.
"She says I can't breathe," Waddell said.
Crystal thought the oxygen tanks had run out and she ran back inside for help. She says the staff came out with more oxygen, but nobody seemed to know CPR.
"They didn't do no CPR or anything," Waddell said. "They were just rubbing her chest.
"When the dentist came out she started yelling 'I told you to take her to the hospital' so I yelled back at her 'I have to get her in the car in order for that to happen.'"
Instead an ambulance was called but April could not be saved. Now the family just wants to know what happened. The results of an autopsy are pending.
"A 46-year-old woman should not die in the parking lot of a dentist's office," Waddell said.
Although FOX 2 was unable to talk to the dentist, we're told an investigation is underway.
"We feel deeply for what happened," said Caroline Oldsey, who works at the dentist office’s human resources office. "Our thoughts go out to them. Our thoughts and prayers are with them."
"Our hearts go out to the family and our prayers," said Dentist Chad Wise. "We are looking at everything that happened that day."
