Translation [partial]:

Sayenko: "Hold on, hold on. Be neater, fuck!" –laughing- "Hold on, hold on, hold on, don't hit him, don't hit him. Watch him…"

Suprunyuck: "What? With what?"

Sayenko: "What, he's still alive? He's still moving his arms after I ripped up his intestines."

Suprunyuck: "He's having a fucked up day."

Sayenko: "Get over here fast. Kill him already."

Suprunyuck: "What?"

Sayenko: "Kill him already."

Suprunyuck: "I already put the hammer back. He's already dead."

Sayenko: "I poked out his eyes and he's still not dead. Get the knife."

Back at car:

Sayenko: "I stuck the screwdriver in his brain. I got him in the nose from his eye. I don't understand how he was alive? I felt his brain."
