Mexican Musician and Family Killed Over Bitcoin Cold Wallet Believed to Hold Millions

Mexican prosecutors say keyboardist Jonathan Meléndez, a member of the band Camilo Séptimo, was fatally attacked at his home in Atizapán de Zaragoza on September 1 along with his pregnant wife, their three-year-old daughter and a domestic worker. The family’s six-year-old son survived the incident. Authorities recovered the four bodies at the residence and began an investigation into the motive behind the killings.

State prosecutors allege the assailants entered the home seeking a cold wallet that they believed held substantial Bitcoin holdings. Investigators say one suspect, identified as Diego Sebastián and described as a business associate of Meléndez, used his relationship with the musician to gain access and recruited a second man, named as Gerardo, offering him 2 million pesos (about $118,000) to help obtain the cryptocurrency. Both suspects were detained on September 2; official documents list their surnames as “N” in line with Mexican privacy rules for criminal proceedings.

Prosecutors and experts note that cold wallets — physical devices that store the private keys needed to move cryptocurrency — do not carry the funds themselves but control access to digital assets. Common hardware wallet examples include Ledger, Trezor and air-gapped models such as Coldcard. While these devices protect against many online hacks, they leave holders vulnerable to crimes that target people in the real world.

The killings come amid a documented rise in violent incidents aimed at crypto owners. Blockchain analytics firm Chainalysis reported 46 violent crypto attacks through late June and said more than $30 million was stolen in the first half of 2026, with home invasions accounting for roughly 37% of the cases it tracked. In a separate June case, two Texas brothers pleaded guilty after holding a Minnesota family at gunpoint for hours and forcing a transfer of more than $8 million in cryptocurrency.
