Hepatitis Cases Spur Safety Measures

Kristen Diane Parker, a surgical technician, cruised for empty operating rooms at the Denver hospital where she worked. Parker would slip into the rooms and steal syringes of fentanyl, a powerful painkiller, replacing them with syringes she had filled with a saline solution. Parker, who has hepatitis C, allegedly had used those decoy syringes - the source of transmission, authorities believe - on at least 23 Coloradans now infected with the liver-damaging disease, according to her confession to investigators.
