In May 2023, the boy, who has only been identified as KK, shot dead nine children and a security guard at Vladislav Ribnikar elementary school in Belgrade.

Eight of the nine children KK murdered were girls.

On Monday, the boy’s father, Vladimir Kecmanoviæ, was given a 14-and-a-half-year prison term, while his mother, Miljana Kecmanoviæ, was sentenced to three years behind bars.

The boy cannot be put on trial because he is below the age of criminal responsibility. He has been undergoing psychiatric care since he committed the shooting.

The father was found guilty of endangering public safety by teaching his son to shoot and failing to secure his gun. He was also convicted of neglecting a minor.

The mother was found guilty of neglecting a minor, but was acquitted of illegal possession of weapons and ammunition.

Both parents denied the charges.

An instructor at a shooting club called ‘Partizan,’ which the father often would take KK to, also received a sentence of one year and three months.

According to Serbian daily Danas, the verdict shows that the parents neglected their son.

"Definitely this could have been prevented if there was no child neglect. It is an important message to society," Ninela Radičević, the mother of one of the murdered girls told Danas.
