O'Barr was further inspired by a Detroit newspaper account of the murder of a young couple over a $20 After his discharge from the Marines, O'Barr continued his painting and illustration as well as doing lots of odd jobs, including working for a Detroit body shop. The Crow sat on a shelf for seven years, but at last someone wanted to publish it: Gary reedof Caliber Press. In The Crow, Eric and his fiancée Shelley are murdered by a gang of criminals. He then returns from the dead to hunt their killers.
