Just before Parnell and Lightsey refused to testify, anguished family members representing victims of a salmonella outbreak traced to PCA pleaded with committee members to take action to protect the nation's food supply.
Documents obtained by the committee include an October 2008 e-mail from Parnell to Lightsey, a response to Lightsey's notifying Parnell of a positive salmonella result and recommending a shipment be placed on hold.
The indictment also charges Michael Parnell, who is Stewart Parnell's brother and a former supervisor, as well as Samuel Lightsey, a onetime plant operator, with many violations related to the company's alleged deceptions.
