Who is the man who confessed to the murder of Mariana Sepúlveda 18 years later: this is how it would have happened
A 42-year-old man appeared before Carabineros in Conchalí, confessing to the disappearance and death of Mariana Sepúlveda, a 19-year-old woman who went missing in 2008. The OS9 unit of Carabineros is investigating his claims and conducting procedures at the Logroño passage, where both the victim and the suspect lived at the time. According to the man, he had an argument with Mariana at her home, which resulted in her death, and he later buried her on the property. In 2013, he exhumed the remains and disposed of them, feeling guilty and deciding to confess. The investigation is ongoing, and the charges may be dismissed after the investigation concludes, meaning the accused cannot be considered guilty until a court issues a sentence against him.
A man has confessed to the murder of 19-year-old Mariana Sepúlveda, who disappeared from her home in Conchalí, Chile, on August 29, 2008. The confession came nearly 18 years after she vanished, with the suspect appearing at a police station and admitting responsibility for her death. According to reports, the man, identified as a 42-year-old resident of the area, claimed he had a conflict with Mariana at his home, leading to her death and subsequent burial on the property. He reportedly exhumed her remains in 2013 and disposed of them, feeling guilty and deciding to confess. Mariana, who was heading to school in the morning, last spoke to her mother, Marta León, saying, “Goodbye, mom, I’m going to school.” She left her home in La Palma, part of Conchalí, around 8:10 a.m., dressed in her uniform. Her family had been searching for her ever since, with the official investigation led by the Public Prosecutor’s Office beginning almost a week later. The search included visits to hospitals and public spaces, with the family being directed to the fifth Police Station due to their connection to the community. The family faced numerous speculations during the search, including claims that Mariana had been taken north and seen with two individuals. However, the theory of kidnapping was dismissed early on. Marta León recalled being told by a police officer that she was not the only parent dealing with a missing child, which added to her emotional distress. The current investigation involves forensic specialists examining the residence where the suspect lived at the time. The case remains under review, and while the suspect has made a formal confession, legal proceedings will determine the outcome. Until then, the truth remains pending.
