Prosecutors Charge Mother, Son Over Guns Hidden With Minors
The Higher Public Prosecutor's Office in Belgrade has indicted Kosta M. (20) and Olgica M. (50). He is also charged with preparing murder, and the guns were kept with minors, the indictment says.
The Higher Public Prosecutor’s Office in Belgrade (VJT) filed an indictment on August 6, 2026, against Kosta M. (20) and Olgica M. (50), son and mother, and forwarded it to the Higher Court in Belgrade for confirmation. Both are charged with illegal production, possession, carrying and trafficking of weapons and explosive materials under Article 348 of the Criminal Code. He is additionally charged with aggravated murder under Article 114, paragraph 2, at the preparatory stage, against one victim.
All the acts described in the indictment took place over eight days, from April 22 to 29, 2026. The victim is under police protection, so his identity has not been released. The minors named in the indictment have not been identified either.
How the Guns Reached the Minors
According to the indictment, Kosta M. obtained an HS pistol, model XDM-9, in 9x19mm caliber, with an empty magazine. He wrapped it in cloth and took it to an apartment where a minor was staying without being registered there, and left the weapon with him for safekeeping.
The second weapon was a Crvena Zastava pistol, model 99, in 9mm PARA caliber, with 11 rounds of ammunition. On April 29, Olgica M. carried it out of the apartment where she lives with her son. She took it to Dušana Vukasovića Street and left it behind a building, wrapped in a towel, for a minor to pick up. That pistol was later seized from the minor.
Both weapons, then, ended up away from the defendants’ addresses and in the hands of people who do not face criminal liability the way adults would. Carrying the second pistol is the only act the indictment attributes to Olgica M.
What the Indictment Says About the Encrypted Chat
The part of the indictment dealing with the preparation of the murder rests on communication through an application for encrypted phone communication. The prosecution’s statement reads:
Using a special application for encrypted phone communication, Kosta M. communicated in a group chat with individuals registered as “Camorra,” “Sparta1010” and “KGB CRVENI,” in connection with the liquidation of the victim.
Alongside the messages came surveillance of the target. Kosta M., the indictment states, tracked the victim’s movements as agreed with the other members of the chat, photographed his business premises and sent those photos to the group chat.
On the last day of that period, direct contact was also attempted. From the same statement:
He tried to arrange a direct meeting with the victim by calling him on his mobile phone on April 29, 2026, and repeatedly insisting on setting up a personal meeting, introducing himself under a different name in order to arrange an encounter with him for the purpose of taking his life.
The meeting never happened. The prosecution classifies the call made under a false name as an act creating the conditions for direct execution of the crime, which is why Kosta M. is charged with preparatory acts rather than attempt.
Second Indictment This Week Built Around an App
This is the second case in under a week where the same prosecutor’s office has built an encrypted app into the very description of the offense, not just into the evidence. In early August, the VJT announced an indictment against Uka R. (28) and Enis S. (21) over two bombs thrown at the Belgrade restaurants “Babaroga” and “Džeri” in February, in which the explosives, according to the indictment, were sourced through Signal.
The difference lies in who physically holds the means used to carry out the crime. In the bombing case, the device stayed with the defendants until the attack. Here, the weapons were moved out immediately, first to one address and then another, and placed with minors who are never described as participants in the planning.
What Comes Next
The prosecution has asked the Higher Court in Belgrade to extend the defendants’ detention, arguing there is a risk they could reoffend within a short period. The court is now deciding whether to confirm the indictment.
Guilt has not been established. Kosta M. and Olgica M. are presumed innocent until a final verdict.
