金正男
According to South Korean intelligence sources, Kim Jong-un had issued a standing order to have his half-brother killed. In 2012, there was another assassination attempt on Kim Jong-nam, who later that year sent a letter to his half-brother begging for his life. In late 2012, he appeared in Singapore one year after leaving Macau. He left Macau on suspicions that he was being targeted for assassination by Kim Jong-un; South Korean authorities had formerly indicted a North Korean agent, Kim Yong-su, who confessed to planning an attack on Kim Jong-nam in July 2010.
