Diego Sebastián “N” has been identified as the material author of the murder of Jonathan Meléndez, keyboardist of the band Camilo Séptimo, and his family. His life in Mexico, marked by an expedited naturalization and multiple business ventures, culminated in a horrendous crime in Atizapán de Zaragoza on September 1, 2026.
Diego Sebastián “N” was born on March 26, 1975, in Buenos Aires, Argentina. Without a criminal record in his home country, he became a Mexican citizen in 2001 through the National Population Registry. At the age of 26, he founded his first company, Ferlini, Rosen y Asociados, S.A. de C.V., focused on the buying and selling of medical materials. In 2004, he changed the company’s name to Comarketing Farmacéutico, S.A. de C.V., specializing in medical consulting.
During his business career, he also established Shark BTL in 2003, a marketing agency. In 2006, he began to face legal issues with his first criminal case in Mexico, although the exact charge is unclear. Over the years, he set up several more companies, including Medical Branding de México, S.A. de C.V. in 2008, and Fifty Fifty Total Production, S.A. de C.V. in 2018, alongside his partner Paola Mandri.
Diego Sebastián “N” faced multiple banking litigations, with at least four lawsuits in 2019 related to Shark BTL. Despite his legal difficulties, he continued to expand his businesses, including ties in the vacation rental sector that connected him to Jonathan Meléndez.
On September 1, 2026, Diego Sebastián “N” was accused of planning and executing the murder of Meléndez and his family. Investigations suggest that this attack was premeditated, with Diego seeking materials to subdue the victims. The violence of the crime continues to shock the community.
This case highlights the complex history of Diego Sebastián “N,” an individual with a long business and legal trajectory that culminated in an act of extreme violence, reflecting the urgency to address security and justice issues in the country.
