Vasili Mitrokhin reports that on 7 May 1975 the border patrol officers detained a suspiciously-looking young man, between 20-22 years of age, for trespassing on the border zone in the village of Lunka, Glybovsky District, Chernivsty Oblast, who identified himself as Muntianov Boris Borisovich, resident of Odessa. His likeness did not match the passport photo and the officers asked that he follow them to the local security checkpoint. Muntianov resisted and attacked one of the officers, hitting him in the face. He headed for the deep forest and was able to escape.
Searching the area, officers retrieved the trespasser’s rucksack that contained the Russian-English dictionary, a chocolate bar, flashlight, batteries, large-scale map of Chernivtsi Oblast, electric razor, binocular, four passports with different surnames, birth certificate, work-book, and a registration card issued to Petraukas Zigmas Yuzovich, native of the Lithuanian Soviet Socialist Republic. The Lithuanian KGB informed that Petraukas is a wanted criminal. Local residents of Novoselitskoe and Glybovsky districts actively assisted in the search of Petraukas. On May 8, fifteen search teams with trained dogs scanned the forest. Petraukas was intercepted near the village of Marshynitsy, approximately five kilometers away from the border. Petraukas confessed during questioning that he was dissatisfied with the life in the USSR and was planning to escape via Romania to a capitalist country. The testimony was confirmed through the interior investigation in his cell.
