 Two different actresses played Prestons wife. The "condemnation  archive footage" was filmed first, and featured Alexa Summer (qv).  However, when it was time to film the scene where she was arrested,  she could not be found. Maria Pia Calzone (qv) had to take her  place. As a result, theres two separate credits, Summer is credited  as "Viviana Preston", while Maria Pia Calzone was credited as  "Prestons Wife", even though they are supposed to be the same  character.
