A police report seen by The Associated Press said the family of the 50-year-old Gicheru found him unconscious at his home Monday night. “The body was found lying on the back, clean, casually dressed and no saliva or blood on any body opening,” the report says, noting that “the deceased is a known diabetic and high blood pressure patient.”

The police report noted that Gicheru’s 20-year-old son, who told his mother that Gicheru “had taken something,” was later found with “froth” coming from his mouth and difficulty breathing. He was in stable condition at a local hospital, the report said. It was not clear what happened.

In comments to reporters, family lawyer John Khaminwa said the family had described Gicheru as stressed in the hours before his death. “He was not himself,” Khaminwa said. The family intends to bring in pathologists to “look at his internal organs and other things,” he said.

The Kenya Human Rights Commission said it was “concerned with the shocking news of the untimely death” and urged a swift and conclusive investigation.

The charges against Ruto and others, including previous President Uhuru Kenyatta, were dropped in 2016 when the case fell apart amid allegations of witness interference. Ruto denied the allegations against him. The court’s decision to drop the case specified that it did “not preclude new prosecution in the future.”

Ruto was chairing his first Cabinet meeting on Tuesday after being sworn in on Sept. 13 following a narrow election win.

ICC spokesman Fadi El Abdallah said he could not comment on Gicheru’s case but only on the procedure to be followed: “If there is information about the death of an accused, a confirmation of this information should be submitted to the (trial) chamber and then the chamber issues a decision ending the case.”

Judges are currently considering their verdicts in the case. No date had been set for a hearing to deliver the judgment.
