The Johns Creek police officer who worked to revive the woman while waiting on an ambulance, said he was frustrated by the series of mistakes leading up to her death.
Johns Creek police Cpl. James Harris raised a red flag after Dukes died at 3:01 p.m., noting the discrepancies in the response time.
"I saw what had happened, and said, 'Not on my watch,' " the 17-year law enforcement veteran said Wednesday.
Harris was the second officer to arrive at her home 25 minutes after she placed her call.
They found Dukes not breathing and began administering CPR while Harris, a fellow officer, and Fulton County Fire paramedics also at the scene called repeatedly for an ambulance.
"The firemen had already been asking for an ETA," with no response, Harris said.
When he tried to get help on his police radio, he was told the nearest ambulance was about 13 minutes away.
"I said, 'That's not good enough! We've got a woman in full arrest,'" Harris said.
Twice before the ambulance arrived, Dukes' heart began beating again, but she kept slipping away.
Hours after Dukes died Saturday, Harris requested records from Fulton Emergency Management Agency to learn more about what led up to the incident.
When Fulton EMA refused, he filed a written request for the audiotape of her call to 911 and transcripts, both of which are public records. He was still waiting for them on Wednesday night.
