A Guatemalan court overseeing the genocide case against former dictator Efrain Rios Montt has heard testimony that he suffers from dementia.
Walter William Rinze Turton is part of a medical team that evaluated the 89-year-old former general in recent days as the court considers whether he is fit to stand trial.
Rinze told the court Tuesday that the team determined Rios Montt has dementia related to heart disease and high blood pressure.
Prosecutors accuse Rios Montt of responsibility for the killing of 1,771 Mayan Ixil people by security forces under his 1982-83 regime.
He was sentenced in 2013 to 80 years, but the conviction was later overturned.
Rios Montt’s legal team argues he is not able to understand the proceedings or assist his defense, and thus not competent for retrial.
