(CBS/AP) CONCORD, N.H. - David Kwiatkowski, a traveling hospital technician accused of infecting dozens of patients with hepatitis C through tainted needles, told investigators he had been stealing drugs for more than a decade and was "killing a lot of people," according to a plea agreement filed Monday that would send him to prison for 30 to 40 years.
Kwiatkowski, who has been jailed since his arrest in July 2012, is accused of stealing painkiller syringes from Exeter Hospital's cardiac catheterization lab and replacing them with saline tainted with his blood. He has agreed to plead guilty to the 14 federal drug theft and tampering charges he faced in exchange for a lighter sentence. Had he been convicted at trial, he could have been sentenced to up to 98 years behind bars.
Thirty-two patients in New Hampshire have been diagnosed with the strain of hepatitis C carried by Kwiatkowski, who worked at 18 hospitals in seven states before being hired in New Hampshire in 2011. There have been seven cases in Maryland, six in Kansas and one in Pennsylvania. One of the Kansas patients has died, and hepatitis C, a blood-borne viral infection that can cause liver disease and chronic health issues, played a "contributing role," the plea agreement said.
Linda Ficken, of Andover, Kansas, is among those Kwiatkowski is accused of infecting. Ficken, 71, said Monday she's glad he pleaded guilty but wishes the sentence were longer.
"It should've been life, since he gave us potentially a death sentence," Ficken said.
More than a year after Kwiatkowski's arrest, Ficken said, she is still angry at him and at the system that let him move from job to job after he was fired over allegations of drug use and theft.
The plea agreement includes details of an interview Kwiatkowski gave investigators in New Hampshire after his arrest in which he said he knew he'd been diagnosed in 2010 but continued to "swap out" syringes of the painkiller fentanyl. He said he had been stealing drugs since 2002 and estimated that he had swapped syringes at least 50 times in New Hampshire, at least 30 times in Georgia and more than 20 times in Kansas. Under the plea deal, Kwiatkowski would avoid criminal charges in the latter two states.
Asked if anyone helped him divert drugs in Exeter, Kwiatkowski said, "It was all me." He then added, "and I'm going to kill a lot of people out of this," the plea agreement states. Asked to clarify his comment, he replied, "I'm killing a lot of people."
Kwiatkowski, who grew up in Michigan, worked as a traveler sent by staffing agencies to hospitals around the country, usually for temporary jobs. In announcing federal drug charges last year, U.S. Attorney John Kacavas called him a "serial infector."
Kwiatkowski's attorneys did not immediately respond to emails or a phone message left at their office Monday night.
A hearing on the plea agreement is set for Wednesday.
