Husband and wife Natalia Baksheeva and Dmitry Baksheev were arrested after seven bags of body parts were allegedly found in their freezer.
Now there are fears the Russian couple used some of their victims' body parts as meat in pies that Natalia sold to restaurants.
Neighbours say former nurse Natalia made and sold pies to boost her income, boasted to cafe owners that she could supply "meat", and may have worked as a chef.
