On May 30, 1979, Avdonin’s team dug into the site. They saw human bones and removed three skulls. They knew that some tests needed to be done but what kind they didn’t know. The skulls were cleaned with water, they were gray and black; and in areas appeared etched with acid. The central facial bones of all the skulls were missing and some skulls had large round holes as if damaged by bullets.  These three skulls were taken secretly to be tested in Moscow.
