Two individuals, identified as Diego Sebastián and Gerardo, are facing charges in connection with a quadruple homicide in Mexico, allegedly motivated by an attempt to steal a Bitcoin cold wallet containing millions of dollars. The suspects are scheduled for a court hearing on Wednesday to determine if proceedings will continue.
Prosecutors from the Attorney General’s Office of the State of Mexico (FGJEM) accuse the men of killing Jonathan Meléndez, the keyboardist for the rock band Camilo Séptimo, his pregnant wife, their daughter, and an employee at their home in Atizapán de Zaragoza. The family's dog was also killed.
According to reports, one of the suspects was a business associate of one of the victims and allegedly used this connection to gain access to the residence. If convicted, the suspects could face sentences ranging from 25 to 70 years in prison for each homicide.
This incident highlights a concerning trend of "wrench attacks," where individuals are subjected to violence or threats to coerce them into revealing cryptocurrency holdings or wallet access. Blockchain security firm CertiK reported a significant increase in such attacks, with 20 publicly reported home invasions targeting crypto owners in the first half of 2026, up from a single incident in the same period the previous year. Globally, CertiK identified 52 wrench attacks in the first half of 2026, a 33.3% rise from the prior year. These attacks resulted in over $30 million in stolen cryptocurrency during the first half of 2026, according to Chainalysis.
