According to an investigation report, 25-year-old Daniel Ray Stewart of 825 Branson Street, was found in the emergency room posing as a visiting resident in training in October.
Stewart was discovered when a physician's assistant noticed he wasn't wearing an ID and alerted the Fayetteville Police Department.
In an exclusive interview with ABC11 Eyewitness News Tuesday, Stewart insisted he has the medical credentials to do the job.
He says he's a doctor from the University of Tennessee and a specialist in the Army National Guard out on sick leave.
For about three weeks, he shadowed medical teams at Cape Fear Valley Medical Center and gave medical advise to physician assistants in the ER and at accident scenes.
"Start IVs, give drugs, very few, and do EKGs and assess heart and lung functions," Stewart said.
He says he responded to three to six calls a day working closely with other medical personnel who were treating patients.
"My job is to observe and be a helping hand if needed and to further medical assessment," Stewart said.
Stewart says he completed his medical training and received his degree last year.
"I went to school at the University of Tennessee ... I graduated from the Graduate School of Medicine," he said.
ABC11 checked with the University of Tennessee and they said they have no record of Stewart completing medical school.
A spokesperson with Cape Fear Valley says Stewart was under direct supervision at all times and was never alone with a patient.
The hospital has launched an internal investigation to determine just how many patients Stewart may have seen or been involved with.
Stewart has been charged with three counts of impersonating a doctor.
The spokesperson with the hospital also says Stewart has a history of similar activity or impersonation.
