A resident of a Vermont retirement community made ricin and tested the deadly toxin on her neighbors by putting it on their food or in beverages over a period of weeks, investigators said.
Betty Miller, 70, told an FBI agent that she wanted to "injure herself" and was testing the poison’s effectiveness on other residents at the Wake Robin senior living facility in Shelburne, according to a criminal complaint filed in federal court on Thursday.
Police were called to Wake Robin on Tuesday after Miller told heath care providers she had manufactured the ricin and placed it on other residents' food and beverages, the agent said in the complaint. No residents reported symptoms of ricin poisoning, he said.
The FBI and the Vermont Department of Health interviewed Miller on Tuesday evening at the University of Vermont Medical Center, federal law enforcement authorities said in a statement.
