Belgrade: A Serbian court on Thursday found the parents of a teenage school shooter guilty of his neglect and abuse, reinstating a lengthy jail sentence after a high-profile retrial.
The killings of nine students and a security guard in the Belgrade elementary school on May 3, 2023, shocked the Balkan nation.
Despite high levels of gun ownership in Serbia, mass shootings are rare.
The Belgrade Higher Court, in its retrial on Thursday, sentenced the boy's father, Vladimir Kecmanovic, to 14 years and six months in prison and his mother, Miljana Kecmanovic, to two years and 11 months.
Both were found guilty of "neglect and abuse of a minor", while the father was also convicted of "serious offence against public safety", the court said in a statement.
They can appeal their sentence.
The parents of the boy, who was just 13 when he committed the crime, were first sentenced by the same court in December 2024, handing them similar sentences.
But a Serbian appeals court last November quashed their convictions, citing unclear and contradictory reasoning in the judgment, ordering a retrial.
The trial was held solely against the parents, as their son, who has been placed in a psychiatric institution, cannot be criminally prosecuted due to his age.
The father remains in detention, where he has been held since shortly after the shootings, while the mother is free until a final verdict.
The earlier appeals court also upheld the first-instance acquittal of the boy's mother on weapons charges while it reduced the sentence for an instructor at the shooting range, where the father took his son, to one year in prison.
