DENVER -- A woman suspected of knowingly transmitting a dangerous blood disease will stay in the Jefferson County jail as federal prosecutors consider several criminal charges.

Kristen Diane Parker, 26, a surgery technician at Rose Medical Center in Denver and Audubon Surgery Center in Colorado Springs, was denied bail after the judge ruled that she was a danger to her community.

Parker had Hepatitis C and is accused of injecting herself with painkillers meant for patients, then filling the used syringes with saline solution, which were later used on patients.

Up to 6,000 patients from Rose Medical Center and Audubon Surgery Center have received letters warning them of possible exposure to hepatitis C. Parker worked at Rose Medical Center from Oct. 21 to April 13 and at Colorado Springs Audubon Ambulatory Surgery Center from May 4 until last week.

Ten hepatitis C cases have been linked to Rose hospital.

Parker waived her right to a preliminary hearing Thursday but the issue of bond was discussed, in great detail, during her hearing in federal court.

Magistrate Judge Craig Shaffer decided not to let Parker out of jail, saying, "There is no combination that would assure that you are not a danger to the community."

Parker didn't say much in court Thursday, but the DVD recordings of her police interviews spoke volumes.

This is a courtrom blog of the proceedings:

12:50 p.m.

Parker denied bond after judge rules she's a danger to the community.

In a recorded DVD interview conducted on June 30 with a Denver police detective, Parker admitted to using heroin in New Jersey where she lived from July through September 2008.

Parker said she thought that was when she may have contracted Hepatitis C.

In the interview, she told the police detective that she would use the drug fentanyl at work, on lunch breaks and at home, even bringing the needles back to the hospital after injecting the painkiller into her arm.

"I have a couple of times. I would mainly keep it on myself and switch it out. If I had two in my pocket I'd just grab one, not knowing if that was the clean one or not," she said in the recording.

Although told by Rose staffers in October 2008 that she had hepatitis C, Parker told the detective in the recorded interview she never went to see her personal doctor to follow up.

"I guess it kind of got pushed down the list. At that time, I didn't have insurance. I had no symptoms. It never crossed my mind I might be sick. It's not like a dismissal but kind of like, 'Well, it's not that serious,'" Parker said.

At one point during the recorded interview, Parker cried.

"I didn't know that this was going to happen. I mean, to the extent people would get sick for the rest of their lives because of me. And I can't take it back," Parker said, sobbing.

Parker would go on to tell the detective that Rose staffers could have done more to make it harder for her to steal the medicine.

"If (the drugs) were locked up or on the doctor's body or what not, then you really have nothing to worry about," Parker said.

Her father, Bill Parker, also testified in court.

The judge asked him if he had recommended Kristen take a follow-up blood test. Bill Parker told Shaffer he did not urge such a test.

"I remember they told her it could be nothing. She didn't perceive it as that serious," Bill Parker said.

According to the Centers for Disease Control and Prevention's Web site, "Fentanyl is estimated to be 80 times as potent as morphine and hundreds of times more potent than heroin. It is a drug of abuse."

11:05 a.m.

Mary LaFrance is with the Federal Drug Administration, office of criminal investigations. She takes the witness stand.

Her office started an investigation started on July 1, when Parker was employed as a scrub technician in.

Special agent LaFrance met with the DEA, Denver police and Rose management on July 1.

Parker admitted switching out Fentanyl syringes at both facilities -- Rose and Audubon -- LaFrance said. Denver police detective Dale Walker interviews Parker.

10:55 a.m.

Preliminary hearing and detention issues are heard.

Parker waives her right to a preliminary hearing.

The judge then explains Parker's rights to her, especially that she has a right to make the government prove they have enough evidence to advance the case.

Judge Shaffer explains that he could dismiss all charges against her if the government failed in its duty. Parker affirms her intent to waive her right to the hearing.

On the issue of bond: pre-trial services recommends releasing her to the custody of her parents, under monitor of an ankle bracelet, with drug testing, and treatment for drug addiction.

The government calls a special agent to the stand on the bond issue.

10:35 a.m.

All activity has ceased as attorneys shuffle between courtrooms on other, unrelated matters.

With braided pony tails split to each side and a multi-colored tattoo on her upper neck, Kristen Parker entered Judge Craig Shaffer's courtroom at 10:05 a.m. Even before it began, there was plenty of emotion on display.

One attorney yelled profanity at others before the judge entered, complaining that something "was (expletive) wrong and you know it!"

A courtroom observer spoke to another reporter, saying "This whole thing is b…..t. And you don't know the half of it. I had my (breasts) removed ... and now this. Imagine having your (penis) removed. It's not any fun."
