KISSIMMEE, Fla. -

The defense has rested on Wednesday in the trial for Matthew Scheidt, the teen accused of pretending to be a physician assistant in Osceola County, with hospital employees discussing how they were deceived.

Scheidt is charged with two counts of impersonating a physician assistant and four counts of practicing medicine without a license. He is pleading not guilty.

The state presented several more witnesses in the case against Scheidt, including one of the hospital human resources employees who mistakenly gave Scheidt an employee badge that gave him access to the emergency room at Osceola Regional Hospital in September 2011.

On Tuesday, Osceola Regional Medical Center employees described how 17-year-old Scheidt deceived them in August 2011 by pretending to be a physician's assistant and requesting a new hospital badge because of changing offices.

Scheidt later presented himself to a nurse at the hospital emergency room as a physician assistant student at Nova University and said he was working with Dr. Ramirez, assisting him in the office and the operating room, according to police.

Registered Nurse Adam Friends said he had seen Scheidt in the emergency room on several occasions so when a patient stopped breathing, he asked Scheidt to step in.

"He stepped in and started doing chest compressions on the patient," Friends said in court on Wednesday.

While in the ER, Scheidt conducted exams, provided patient care and accessed restricted patient information, Kissimmee police said. The Human Resources Department became concerned about Scheidt's qualifications when he continually requested access to restricted areas of the hospital.

A check into his qualifications showed that Scheidt worked for Surgical Management Group as a part-time billing clerk, not a physician assistant.

Jurors on Tuesday were also played the two-and-a-half hour interview Scheidt did with investigators, where he said he never lied and the hospital employees were using him as a scapegoat to cover the mistake.

"I specifically remember putting on that paperwork that I was an assistant and I put back slash clerical work or clerical," Scheidt had said in the interview. "I want to find out who did this and put that into the system and have whoever that is fired because apparently they're too ignorant to have that position."

Scheidt also faces more charges for impersonating a police officer and two counts of carrying a concealed weapon after he was arrested in Miami Beach in January. He is currently being held at the Osceola County Jail on no bond.

Scheidt faces up to five years in prison if he is convicted on any of the charges.
