Wake County officials made the announcement at a news conference Tuesday morning. Officials said the county took over at the request of the Six Forks EMS board.
Wake County Manager David Cooke told ABC11 that an investigation of the company's finances by the Raleigh Police Department is underway.
Cooke said Six Forks officials have not produced a 2010 audit that was due in November. He said officials went back and discovered that the 2009 audit was fraudulent and had the signature of an accountant who does not do audits.
"We kept pushing them because of the way we're going to budget rescue squads this year. There was a big push to make sure that audit got done. The longer that went on, with the inability to get it done, it simply raised more questions about the 2009 audit - to look at that in a little more detail - and find out that that was done fraudulently," said Cooke.
Six Forks EMS Treasurer Ed Fuller has resigned and bookkeeper Jill Cafolla is on leave while the investigation continues.
No charges have been filed.
Six Forks EMS had stations on Lynne Road, Norwood Road, Mt. Herman Road, and shared a location with the Raleigh Fire Department on Pleasant Valley Road.
Dr. Brent Myers, director of the Wake County Department of Emergency Medical Services, said Tuesday there are no indications there were any problems with emergency calls made by Six Forks EMS.
"We have access to every single patient's care at a moment's notice and we have an aggressive system to make sure that patient care is at the high level that we always anticipate. And we have absolutely no reason to believe that there was anything but the highest level of patient care throughout," said Myers.
