Establishing justice for the victims of international crimes and their prevention

We work so that

The national law enforcement bodies better investigate war and other international crimes committed in Ukraine.

The persons who committed war and other international crimes in Ukraine are brought to national and international justice.

War crimes victims have an opportunity to give evidence.

These three goals stem from 9 years of experience in documenting and investigating international crimes and serious human rights violations, committed in the context of armed conflict in Ukraine and other regions of Eastern Europe, Caucasus and Central Asia affected by conflicts.



Since February 24, 2022 we have been daily monitoring open sources for events and registering the event that might contain signs of war crimes.

So far, we have recorded


such incidents.

We carry out field missions to collect evidence of international crimes and serious human rights violations, committed in the context of armed conflict in Ukraine and other regions of Eastern Europe, Caucasus and Central Asia affected by conflicts.

We had over


such missions since 2014.

While documenting we make sure that the ‘probativeness’ of evidence is preserved, so that later it`s not rejected due to irregularities in the evidence-collecting.

We look for probable war criminals, based on the eyewitness and victim evidence from the field missions, open data and OSINT.

This combination allows for greater accuracy of conclusions and makes a strong case for investigations and future trials.

We investigated


potential war crimes.

Preserving and systematization

All the documented information is entered into the I-DOC database. Since 2018 we have entered information about:


incidents with signs of war crimes

What is  I-DOC and why is that important?

The evidence gathered is entered into the I-DOC data base, a tool for working with evidence related to serious human rights and international criminal law violations.

After a document is imported into the data base, the facts from this document are recorded in forms belonging to various categories and groups. I-DOC contains not only detailed information on the circumstances of potential war crimes, victims, and witnesses, as well as on persons suspected of committing these crimes, but also is a robust analytical tool enabling to rapidly link stand-alone events with the persons involved in them.

Unlike other data bases I-DOC provides capabilities to build criminal cases in linked with the international criminal law. The data base was developed using the experiences of the ICC international crime investigations, its architecture echoes the logic of actions in such investigations.

Working with
actors of justice

We liaise with the representatives of the prosecution office, the National police investigators, the Security Service of Ukraine and the judiciary. This cooperation is aimed to improve the quality of official investigations and to advance justice through:

Training and Mentorship

Unification of prosecution strategies

Expanding and Strengthening Evidence

Training of Judges

Participating in Investigative Actions

Truth Hounds are continuously liaising with foreign prosecutors and investigators regarding the cases that could be opened on the basis of one of the extraterritorial jurisdiction principles.

We also provide consultations to foreign Governments on present challenges and prospects of war crimes documentation and investigations, as well as the prosecution of perpetrators.

We deliver trainings for Ukrainian prosecutors, investigators, judges, and human rights activists who deal with war crimes.

Since 2018 we have delivered


trainings, educational events and lectures on international humanitarian law, documentation methods and international crime investigations.

Owing to robust collaboration we have an opportunity to track further education progress of the Ukrainian law enforcement officers in the field of international humanitarian law and international crime prosecution.

Cases prepared and analysed by Truth Hounds are a major part of war crimes prosecutors` and investigators` portfolios.

We communicate with the prosecution authorities almost every day. We became their key advisors in certain areas related to war crimes.
