The former Exeter Hospital medical technician accused in a hepatitis C outbreak was fired from a hospital in Pennsylvania in 2008, and again in 2010 while working at an Arizona hospital, where he was discovered unresponsive in a locker room with syringes and needles on him. David Kwiatkowski, 33, was fired in 2010 after working as a radiation technician for 11 days at Arizona Heart Hospital in Phoenix, according to a hospital statement. Two years earlier, he was let go from his contract job as a radiology technician at UPMC Presbyterian in Pittsburgh in 2008 after the hospital said he was found in an area where he wasn't assigned.
