Daiane Alves Souza, a 43-year-old real estate broker, was murdered by her building manager, Cléber Rosa de Oliveira, 49, who confessed to the crime after being arrested. Shortly before her disappearance on December 17, Daiane had recorded the assault by the building manager. The cellphone, which held key evidence of the attack, was thrown into a sewer by the perpetrator and was only discovered 41 days later, on January 30, coincidentally two days after her body was found.

The investigation reveals significant delays and complications in the case, with the police facing challenges in locating the cellphone until it was eventually retrieved. The releasing of the recording from the cellphone sheds light on the events leading to Daiane's tragic death and highlights the potential evidence that could play a critical role in the ongoing legal proceedings against Oliveira. The information gathered from the phone could significantly impact the testimonies and the direction of the case.

Meanwhile, Oliveira's defense claims they have yet to access all the investigation documents, particularly the final report, and say they will respond accordingly once all materials are reviewed. This statement points to procedural issues in the investigation and possible delays in the judicial process, raising concerns over the impact on justice for Daiane and accountability for her murder.
