"In the absence of modern equipment local experts were unable to establish objective reasons of the people's death," the investigative commission said in its account available on the website.
"Only with the assistance of international experts it will be possible to find out if there were hazardous substances in the bodies of the victims who died in the building of the Trade Unions in Odessa," the commission said.
The commission reported that 48 forensic examinations of the bodies killed in Kulikovo field square had been carried out. All in all, 85 forensic examinations and 160 other tests were appointed, the commission said.
On September 4 Chairman of the commission of the Odessa regional council Grigory Yepur said that the commission had disbanded itself. The investigation has been conducted by the Prosecutor's General and the Interior Ministry of Ukraine which are not accountable to deputies of a local level, Yepur said.
On May 2 the militants of Pravy Sector and the so-called self-defense forces of Kiev "Maidan" crashed a tent compound on Kuikovo Pole square, where federalization supporters had been collecting signatures in support of a referendum. Then, the militants set fire to the building of the Trade Unions, where representatives of the opposition to Maidan found shelter. Forty-eight were killed in the clashes and more than 200 were wounded.
