Was Cain's gang holding the Elvis Presley skeleton for RANSOM?
This is one of the many objects Robocop sees when he enters Cain's lair: a glass case holding the apparent skeletal remains of Elvis Presley, complete with picture.
This always baffled me, and I wondered why Cain would have this, of all his possessions. Did he steal it and hold it to ransom for millions? How did he get hold of it in the first place?
