DETROIT (AP) — A Massachusetts pharmacist charged with murder in the deaths of 11 Michigan residents from a 2012 U.S. meningitis outbreak has agreed to plead no contest to involuntary manslaughter, according to an email sent to families and obtained Friday by the Associated Press.

The deal with Glenn Chin calls for a 7 1/2-year prison sentence, with credit for his current longer sentence for federal crimes, Johanna Delp of the state attorney general’s office said in the email.
