Police found Galeana's body in a closet in the suspect's apartment last week after her family lead police to the building. Prosecutors said she had been strangled and partially dismembered.
When asked if Calva had eaten the woman, prosecutor Gustavo Romulo Salas said: "That is the assumption that exists."
Police said that a search uncovered an unfinished novel by Calva titled "Cannibalistic Instincts." One witness, whose name was withheld by officials, said Calva was fascinated by witchcraft and explicit and sadistic literature.
