Boston's U.S. attorney today will announce what authorities say is a new development in the probes into Framingham's New England Compounding Center linked to last year's fungal meningitis outbreak. The firm's steroid drugs have been linked to 751 meningitis and other infections across the country.

Surviving victims of last year's meningitis outbreak are waiting to see whether authorities announce criminal charges for anyone involved with New England Compounding Center. The FBI recently asked people who got one of the tainted shots from the center to fill out a questionnaire about the injections and their illnesses.
