Two of the three suspects arrested for murdering, dismembering and eating their victims in the northeastern Brazilian state of Pernambuco made a home movie of their crimes, including cannibalism scenes, media reports said.
Jorge Beltrao Negromonte da Silveira, a 51-year-old actor, writer, musician and martial arts instructor, and his wife, Isabel Cristina Pires da Silveira, 50, made a 53-minute home movie titled "Espirito."
The couple is under arrest in Garanhuns, a city about 234 kilometers (145 miles) from Recife, the capital of Pernambuco.
The movie, which may have been made several years ago, tells the story of "Hellen," a woman tormented by the ghost of her husband, played by an actor named Emanuel Silveira, the Folha de Sao Paulo newspaper reported on its Web site.
Investigators have not yet figured out whether the scenes are real or fictional in the movie, whose production date has not been determined, Folha de Sao Paulo said.
The couple and 25-year-old Bruna Cristina Oliveira da Silva, who was identified as Negromonte da Silveira's mistress and lived with them, told police they consumed victims' remains and made turnovers from human flesh that they sold in the city.
The three suspects told investigators they belonged to a cult that received orders from a "voice" to eliminate "bad" women.
The suspects confessed to murder, cannibalism and taking part in grisly rituals during questioning by police, and some details were released at a press conference Friday by the officer leading the investigation, Democrito de Oliveira.
Police found the remains of two women buried in the yard of the couple's house, which was torched by angry neighbors last Thursday.
Investigators suspect that a 5-year-old girl found at the house may be the daughter of Jessica Camila da Silva Pereira, a 17-year-old who disappeared in 2008 and may be a third victim in the case.
Negromonte da Silveira became a person of interest for investigators after he identified himself as the author of a 2009 book, "Revelations of a Schizophrenic," in which he reveals details of the supposed sect's activities.
The three suspects may have been involved in at least five other murders in Pernambuco, police said.
