Man that was locked and later found is considered to be a Satan by people who locked him. His name is Daba with nickname "Limping Daba". Interesting fact is that old Slavic god Dazbog was also called "Limping Daba" and he was god of war. After the rise of Christianity, god Dazbog (or Limping Daba) was personified with Satan and was considered "A prince on Earth" and God's main enemy.
This is symbolic way to show that character Daba was really Satan himself.
