Cristina Amaral, 44, was allegedly raped in front of her husband Juvenal, 57, as a criminal gang tried to force them to give them a large sum of money.
The couple’s mutilated bodies were found buried in the back yard of their house in Camaçari, north east Brazil, with Mrs Amaral missing several internal organs, including her ovaries.
Daniel Santos Neves, 29 and Carlos Alberto Neres, 25, were arrested with three teenagers, aged 13, 14 and 16 after an anonymous tip-off.
Detective Maria Tereza Santos, head of homicide division said; ‘It appears that the accused practiced cannibalism.
‘Internal organs, including the ovaries and fallopian tubes had been ripped out of the female’s body and other body parts are missing. There is no indication of where these organs are.
‘We found that soft tissue had been deliberately cut and sliced from the bones of the victims. We are also investigating whether consumption took place while the victims were still alive.
‘Forensic experts have not conclusively proved the accused ate parts of their victims, but the evidence is pointing to this fact.’
The bodies of the husband and wife were found decaying and buried in a shallow grave on January 9 after concerned neighbors reported the couple missing.
