A stunning law student and mother stands accused of a chilling series of murders across Brazil, with investigators now labeling her a calculated serial killer who used poison, deception, and her legal studies to evade detection. Anna Paula Veloza Fernandez, 36, is in custody facing πΆπππππΆππΎπΈππ she killed four people in five months, employing methods that shifted from a brutal stabbing to clandestine poisonings as she refined her deadly craft.
Authorities in SΓ£o Paulo and Rio de Janeiro have connected Fernandez to the deaths through a complex web of πΎπππΎπΈπΎπ affairs, financial motives, and alleged contract killing. The chief investigator on the case, Allison Ido, has described Fernandez as a “psychopath” who is “cold, remorseless” and took pleasure in manipulation. Her arrest has sent shockwaves through Brazil, upending the typical profile of a serial offender.
The first victim, according to police, was her 51-year-old landlord, Marcelo Fanao, killed in Guarulhos in January. Fernandez allegedly told investigators she stabbed Fanao during an argument after he threatened her family. She reportedly blocked the room with a sheet so her son and niece would not see, then left the body for days until the smell became unbearable. Police allege she later burned the couch to eliminate odors before finally reporting the death.
“This initial crime is odd when measured against the others,” noted veteran homicide investigator Chris Madonna, analyzing the case. “A knife is very personal, very brutal, and atypical for a female serial killer. It suggests a possible disorganized start before she evolved her method.” The case was initially closed for lack of evidence but was reopened after Fernandez was linked to subsequent deaths.
The alleged second victim, Maria Aparecida Rodrigues, was found dead in her SΓ£o Paulo apartment in April. Investigators believe Rodrigues discovered Fernandezβs πΆπ»π»πΆπΎπ with a married military police officer. In a twisted plot, Fernandez allegedly posed as Rodrigues to send ππ½πππΆππππΎππ messages to the officerβs wife, attempting to frame the officer for the murder. Rodrigues had visited Fernandezβs home for coffee and cake before her death; authorities suspect the cake was laced with a cleaning solution.
Fernandezβs method allegedly evolved further with her third suspected victim. Brazilian police told outlet Globo that 65-year-old retiree Nilson CorrΓͺa da Silva died in April after eating a poisoned feijoada, a traditional stew. Investigators assert Silvaβs own daughter, Michelle Paiva da Silva, a classmate of Fernandez, paid her approximately $700 to travel from SΓ£o Paulo to Rio de Janeiro and carry out the killing. Text messages between the two women reportedly confirm the plot.
In a disturbing development, Globo reports Fernandez admitted to poisoning ten dogs beforehand to test dosages of a banned pesticide similar to rat poison, which was later found during a raid on her home. “The fact she tested on animals shows she was learning from the first homicide,” Madonna stated. “Poisoning separates her from the crime scene, which is consistent with many female killers who avoid the ‘blood and guts’.”
The fourth victim, Haidar Mahdi, a young Tunisian man, died in May. Fernandez reportedly met him on a dating app, faked a pregnancy to extort money from his family, and then, according to reports from Carta Capital, gave him a poisoned milkshake. His body was repatriated to Tunisia for burial, while the bodies of the other three victims have been exhumed for toxicology analysis to confirm poisoning.
“Exhumation is critical here,” explained Madonna. “Medical examiners can analyze tissue and bone marrow for specific blood markers of poison. It’s a fascinating science that can pinpoint the πππ·πππΆππΈπ and even approximate dosage.” This forensic evidence is key to building the technical case against Fernandez.
The investigation turned decisively when Fernandez herself walked into a police station in April, claiming to be a victim. She reported a poisoned cake left in her law school classroom with a note she attributed to her loverβs wife. This attempt to frame another person backfired spectacularly. “Through this investigation, we concluded that Anna Paula was not the victim, but rather a serial killer,” Chief Inspector Ido told Globo.
Police verified the wife was hundreds of miles away and was herself receiving threats from Fernandez online. Inspector Ido noted that Fernandez tried to use her legal education to manipulate the system. “What made our investigation difficult was that most victims were buried as if they died from natural causes,” he said. Her intellectual arrogance ultimately provided the trail of crumbs investigators needed.
Fernandez is not alone in custody. Her twin sister, Roberta Cristina, is also jailed, accused of advising on how much to charge for a killing and how to stay under the radar. Michelle Paiva da Silva, the daughter of the third victim, is also imprisoned for allegedly commissioning her fatherβs murder. “The person hiring her was also aware of the sadistic nature this personality may have,” Madonna observed. “It raises a lot of red flags.”
The case presents a portrait of an organized offender who learned from each crime, moving from messy, personal violence to detached, calculated poisonings while weaving narratives to divert suspicion. “She kept close after the crimes, which demonstrates the level of control she sought to exercise over everything,” Inspector Ido stated. For now, a community breathes easier as a suspect believed to be a highly manipulative and adaptive killer is behind bars, awaiting the full weight of the justice system she sought to outsmart.
