"Sasha Pastuschak died in Odesa Military hospital without regaining consciousness... He was only 20 years old...
"He was delivered in an extremely severe condition. Coma. Closed head injury. Acute epidural hematoma of the left frontal area. Fracture of the roof and base of the skull... It is terrible that young guys, the blossom of the nation, leave us! The doctors fought to his very last breath, but unfortunately failed. Only his grandparents are left alive... Rest in peace!"
