Jonathan Meléndez, a member of Mexican rock band Camilo Séptimo, was killed with his four-month-pregnant wife, three-year-old daughter and housemaid inside their apartment in Atizapán on Sept. 1, 2026. Investigators are examining reports that Meléndez kept $1.5 million in bitcoin in a hardware wallet at the home and that the killings followed a debt dispute. Two suspects, including a known associate of Meléndez, were arrested within 12 hours. Authorities say both men knew about the wallet and face first-degree murder charges carrying possible sentences of up to 70 years for each victim. The case has drawn attention as an alleged crypto-related wrench attack, in which criminals target people because of known digital-asset holdings.
