SALT LAKE CITY — Alex Wubbels said she couldn't believe what was happening.

"This is crazy. This is crazy. Why is he so angry?" she is heard on body camera video, nearly in tears, as she is being arrested by Salt Lake police detective Jeff Payne.

Wubbels was working her shift as a charge nurse, or a liaison between patients and doctors and hospital managers, at University Hospital's Burn Unit when she was handcuffed in the middle of her work area, pulled outside and put into a police patrol car for about 20 minutes.

She was arrested after refusing to give Payne vials of blood that he needed for an investigation because she said he did not have a warrant or meet any of the mandatory criteria needed for taking blood.

Wubbels was later released and no charges were ever filed against her. But now, Wubbels and her attorney, Karra Porter, want the public to hear her story and see the disturbing body camera video.

On Thursday, Wubbels held a press conference to show the video and called for better training of police officers so that "harassment," as she calls it, of hospital doctors and nurses stops.

"I just feel betrayed, I feel angry. I feel a lot of things. And I am still confused. I’m a health care worker. The only job I have is to keep my patients safe. A blood draw, it just gets thrown around there like it’s some simple thing. But blood is your blood. That’s your property. And when a patient comes in in a critical state, that blood is extremely important and I don’t take it lightly,” she said.

The July 26 incident was caught on the body cameras of Payne and another officer.

"Stop! I’ve done nothing wrong," Wubbels cries out in the video as she's being handcuffed. "This is unnecessary."

The incident began when a truck driver was severely burned in a head-on crash with a vehicle that was fleeing from police in Cache County and crossed into on-coming traffic. The driver of the fleeing vehicle was killed.

The truck driver was sedated and in a comatose state when he arrived at the hospital.

Payne, a veteran Salt Lake police officer, was sent to the hospital by another police agency to get vials of blood for the investigation. But because the patient was not a suspect in the crash nor faced potential criminal charges, because he was unconscious and unable to give consent, and because the officer did not have a warrant, Wubbels — one of the supervisors that night — did not allow him to draw blood.

"If they needed blood, then they needed to go through to proper channels to take it,” she said.

In the body camera video, Wubbels is seen on her phone with numerous supervisors advising them of what was happening and getting confirmation about the policy. Payne sounds impatient in the video and continues to threaten to arrest her.

Wubbels, who is surrounded by other hospital staffers, explains in the video that she is doing what her bosses told her to do. She eventually prints out a copy of the policy for blood draws — one that Salt Lake police agreed to more than a year ago, according to Porter — and shows it to the officer.

Wubbels said close to 10 supervisors were consulted either directly by herself or by the supervisors checking with their own superiors.

But Payne insists he, too, is following orders.

"I'm doing what I’m being told by my boss, and I'm going to do what my boss says," Payne says sternly at one point in the recording.

Wubbels can be seen trying to tell Payne to calm down while telling her boss on the phone that Payne was threatening to arrest her, and that a University of Utah police officer who was present wasn't going to stop him.

"She’s going to jail," Payne says in the video.

"Why?" a hospital staff member asks.

"Interfering with a criminal investigation," Payne replies.

At one point, Wubbels is heard telling her supervisor that she does not feel safe, before telling Payne, "I don’t know why you're being threatening."

"Sir, you’re making a huge mistake right now," a supervisor is heard telling Payne right before he places Wubbels in handcuffs.

"I’m leaving now, with her," Payne declares after being told again he can't have the blood without a warrant. She was taken out of the hospital and put in a police car.
