A 70-year-old retiree in Vermont made ricin and tested the deadly toxin on her retirement home neighbors by putting it in their food or beverages, federal officials said Friday. Investigators said they found the ricin in a pill bottle half-filled with powder and labeled 'ricin.' The powder tested positive for ricin. The FBI said no residents reported symptoms consistent with ricin. Initial symptoms of ricin poisoning are most likely to occur within four to 10 hours of exposure.
