The investigation into the murder of 16-year-old Maja in Mława, Poland, has expanded to include allegations of solicitation of murder against the suspect’s mother, Katarzyna G.

Following testimony from a witness in a Greek juvenile detention center, authorities are investigating claims that Katarzyna G. attempted to arrange contract killings for three individuals: the victim’s father, the family’s lawyer, and an unidentified woman. The witness, Omar, alleged that Katarzyna G. provided photos and locations of the targets, requesting that he ‘finish them.’

During a police search intended to secure electronic data and documents related to these incitement allegations, Katarzyna G. was detained after reportedly attacking and assaulting officers. This has triggered a separate investigation into the violation of an officer’s physical integrity.

While Bartosz G. remains the primary suspect in the murder—facing charges of murder committed with particular cruelty—he continues to deny involvement due to alleged memory loss. The victim’s legal representative, Wojciech Kasprzyk, has raised concerns regarding the prosecution’s previous passivity in addressing death threats and stalking behavior directed at the victim's family. The trial for Bartosz G. is scheduled to begin on October 7 before the District Court in Płock.
