On January 24, Morella escaped from the apartment building and sought help at a women's advocacy agency nearby, prosecutors said.
The case was brought to the public's attention on February 5 when it was published by Venezuelan online news website Cronica Uno.
Neighbours said they saw Morella return to the apartment where she was held captive along with authorities after the report was made.
"She had three changes of clothes inside that apartment, some old shoes, a twin bed on the floor, an old fan, an old TV," said one neighbour who entered the apartment with Morella at the time.
"People attack the neighbours, asking why we did not report it, but we really did not know."
