Gen. Sin Sen, a political and military leader who participated in a failed 1994 coup, died Monday, due to stomach complications and illness, police and family said.
"He vomited with blood, and he did not let me as the wife know about his sickness," said Meas Vy.
Sin Sen, who was 60, was once the national police chief and belonged to the ruling Cambodian People's Party. He joined a coup attempt led by Sin Son, the former Minister of Interior, and Prince Norodom Chakrapong, which failed to topple the government following UN-organized elections.
Sin Sen was later pardoned by King Norodom Sihanouk for the attempt, and he went on to hold key government positions, including parliamentarian, for Funcinpec. He left his position as secretary of state in the Ministry of Interior following July's election.
Sin Sen leaves behind four children and a wife. He was 60. His remains will be cremated on Thursday under the supervision of Interior Minister Sar Kheng.
