Federal agents in Colorado have arrested a former surgery technician accused of exposing up to 6,000 people to hepatitis C.
Authorities say Kristen Diane Parker injected herself with painkillers meant for hospital patients, then filled the used syringes with saline solution. Police say thousands of patients at two hospitals may have been exposed to hepatitis C.
Parker appeared in court Monday to be advised of the charges, which include product tampering and other violations.
Officials say Parker worked at Rose Medical Center in Denver until she was fired after testing positive for the painkiller Fentyl. She then went to work for the Audubon Ambulatory Surgery Center in Colorado Springs.
Authorities say nine patients at Rose tested positive for hepatitis C.
