One of the standard methods of criminal escape involved cannibalism. Pairs of criminals would agree in advance to escape along with a third man (the "meat"), who was destined to become the sustenance for the other two on their journey. Buca also describes the trial of a professional thief and murderer, who, along with a colleague, escaped with the camp cook, their "walking supply":

They weren't the first to get this idea. When you have a huge community of people who dream of nothing but escape, it is inevitable that every possible means of doing so will be discussed. A "walking supply" is, in fact, a fat prisoner. If you have to, you can kill him and eat him. And until you need him, he is carrying the "food" himself.

The two men did as planned--they killed and ate the cook--but they had not bargained on the length of the journey. They began to get hungry again:

Both knew in their hearts that the first to fall asleep would be killed by the other. So both pretended they weren't tired and spent the night telling stories, each watching the other closely. Their old friendship made it impossible for either to make an open attack on the other, or to confess their mutual suspicions.

Finally, one fell asleep. The other slit his throat. He was caught, Buca claims, two days later, with pieces of raw flesh in his sack.

Although there is no way of knowing how often this type of escape occurred, there are enough similar stories, told by a wide enough range of prisoners, from camps from the early 1930s to the late 1940s, to be certain that they did take place, at least from time to time. Thomas Sgovio heard the death sentence pronounced on two such escapees--they had taken a boy prisoner, and salted his flesh after murdering him--when he was in Kolyma. Vatslav Dvorzhetsky was told a similar story in Karelia, in the mid-1930s.
