The charges refer to seven incidents between January and March, and were handed up after prosecutors were twice given more time to present the case to the grand jury. In requesting the delays, prosecutors said they were still conducting interviews and complex scientific analysis in multiple states, though the indictments only address Kwiatkowski's time in Exeter.
Though New Hampshire cannot charge him for possible violations in other states, it can use evidence gathered in those jurisdictions in its trial, Kacavas said.
He said other states are waiting to see the outcome of New Hampshire's case before deciding whether to file charges.
Kwiatkowski, who was arrested in July, had suggested that a co-worker had planted a fentanyl syringe found in his car.
Exeter Hospital officials have said that while employees raised concerns about Kwiatkowski's appearance — some described him as shaky and sweaty — none suspected him of diverting medication. In each case, Kwiatkowski provided plausible explanations related to either personal medical issues or family crises, the hospital said. Kwiatkowski held the required certification for the job and was given good references from his previous two employers.
