(AP) -- Another hepatitis C case has been linked to a Denver hospital where an infected surgery technician is accused of swapping her dirty syringes for ones filled with a powerful painkiller meant for patients.

Colorado health officials said Friday that 11 cases are now linked to Rose Medical Center, where 26-year-old Kristen Diane Parker worked from October to April.

Parker also worked at Audubon Center in Colorado Springs from May until her arrest in June. Some 900 former surgery patients at Audubon have been tested but so far no hepatitis cases there have been linked to Parker.

Investigations also are under way at hospitals in New York and Texas, where Parker also worked.

She is jailed on federal tampering and drug-related charges.
