[20] The court found Landžo guilty, but took into account his young age, immature and fragile personality and mental state when considering his sentencing.
[24] He appeared in a French documentary "Ex-Yougoslavie | Les procès du Tribunal pénal international" broadcast on the Arte channel in May 2021 in which he testified about his participation in crimes when he was a camp guard.
