A glamorous suspected serial killer allegedly kept her landlord’s decomposing body inside her home in Brazil for five days, according to reports.

Ana Paula Veloso Fernandes, a 36-year-old mom and law student from São Paulo, is alleged to have killed at least four people in the space of five months, CNN Brasil reported.

The “extremely manipulative” suspect “takes pleasure in killing” and shows “a lack of remorse,” Police Chief Halisson Ideiao said.

She “wants to kill” and would “certainly attempt to kill others” if released, the chief warned.

One of the four deaths tied to Veloso Fernandes includes her landlord, Marcelo Hari Fonseca, whom she allegedly stabbed during an argument in January.

The case was initially closed due to a lack of evidence, but was reopened when the landlord’s daughter went back to cops — who were eyeing Veloso Fernandes in a series of other deaths, the report said.

She then confessed, according to cops — telling them she covered the entrance to the room with a sheet so her son and niece would not see the body, the report said.

She only called the police five days later when her son began complaining about the smell — and maggots had started crawling around the house.

Veloso Fernandes said she later burned the couch where she stabbed her landlord, claiming she did it to “remove odors” and “clean the room.”

Police have allegedly connected Veloso Fernandes to at least three other deaths between January and May this year, mostly using rat poison, according to the report.

Veloso Fernandes allegedly killed three others — Maria Aparecida Rodrigues, Hayder Mhazres, and Neil Correa da Silva — for financial gain and revenge, according to investigators.

She is accused of first testing the poison on dogs, killing at least 10.

She is being held while testing continues on the exhumed bodies.
