Two suspects in the killing of four people in Mexico allegedly sought a cold wallet they believed held millions of dollars in Bitcoin, news outlet La Jornada reported on Saturday, citing an update from the Attorney General’s Office of the State of Mexico (FGJEM).
Diego Sebastián and Gerardo, whose surnames were withheld, are scheduled for a court hearing on Wednesday, where a judge will determine whether there is sufficient evidence for criminal proceedings against them to continue, reported Diario de México on Sunday.
The FGJEM announced the arrests of the two suspects in a Sept. 2 X post.
According to La Jornada, prosecutors accuse the two men of killing Jonathan Meléndez, keyboardist for rock band Camilo Séptimo, his pregnant wife, his daughter and an employee in their home in the municipality of Atizapán de Zaragoza. The family’s golden retriever was also killed.
The FGJEM said the suspects could face 25 to 70 years in prison per homicide victim if convicted, according to La Jornada.
One suspect was a business associate of one of the victims and allegedly used the relationship to enter the home, Mexico’s security secretary, Omar García Harfuch, said in a Sept. 2 X post.
