When Vayron Jonathan Nakada Ludena went to a Peruvian prison several years ago to visit his older brother, known as the "apostle of death" after being convicted of killing 17 people, the unraveling of his lonely, transient life in Japan was well underway.
Nakada, 30, had taken the news very badly and had grown gaunt. It was his first trip back to Peru since leaving his hometown to become a migrant worker in Japan in April 2005.
"From then on his personality became reclusive, like he was retreating into a shell," Nakada'ssister, Maria Espejo, 48, said in a recent interview at her home in Lima.
