Exeter Hospital, Exeter, NH

The hospital went on to credit itself for its "speedy reporting of this threat to the appropriate state officials" leading to Kwiatkowski's arrest, and criticized other hospitals at which Kwiatkowski worked for not doing so sooner.

"We are saddened that those who reportedly discovered Kwiatkowski's alleged drug diversion activities at other hospitals apparently failed to report them to law enforcement officials," the statement said. "This inaction allegedly resulted in Kwiatkowski being able to secure employment in other hospitals around the country, including Exeter Hospital."

Kwiatkowski worked at multiple hospitals across the country as a traveling technician and in 2008 was spotted lifting his shirt and dropping a syringe down his pants at the hospital he worked for at the time, according to a federal affidavit released last week. Three empty syringes bearing fentanyl labels were found on him during a search, the affidavit said.

Authorities have said they are in contact with eight states where Kwiatkowski previously worked. States that have confirmed their involvement in the multi-state investigation into Kwiatkowski include New York, Maryland, Michigan, Kansas, Georgia and Arizona.
