According to reports, the couple-mistress combination had started these killings by first enticing the victims to the trio’s house with the promise of a job offer, typically as a nanny, or to offer them religious guidance.
The victims were subsequently killed and their flesh consumed once they were inside the house.
Pires would then prepare salgados, a regional meat pastry delicacy, with the leftover flesh as filling.
The victim’s bones were allegedly buried in the trio’s backyard after these meat pastries were sold to nearby residents.
