Eduard "Del" Delacroix was one of the main characters in the novel The Green Mile.
Eduard Delacroix was a death-row inmate at Cold Mountain Penitentiary for murdering his family. After a lengthy trial, he was sentenced to death by electric chair.
While he served his final years, he became friends with some of the prison guards, including Paul Edgecomb. However, Del made an enemy out of Percy Wetmore, the nephew of the Governer of Louisiana, and went through several frequent confrontations with him. Percy frequently called him a "faggot" and at one point broke three of Del's fingers with a nightstick out of sheer impertinence.
Del adopted a pet mouse named Mr. Jingles, who was one of the little things that kept Eduard happy. At one point, Percy stomped down hard on Mr. Jingles, killing him, but a fellow inmate name John Coffey later resurrected him.
Eduard Delacroix's execution was on a stormy night, and it went horribly wrong. After the electrodes were strapped to his head, Percy was tasked with wetting the sponge to conduct electricity to his head, which would making for a quick and painless death. However, Percy deliberately left the sponge dry and placed it onto the electrodes. After Percy ordered that the switch be activated, Eduard went through an agonizing, torturous execution; instead of killing him instantly, the dry sponge caused the alternating current to flow throughout him; the current caused his body to shoot out blue flames. After two minutes, Del died from the electrocution; by this point, his face was on fire.
Later, in retaliation, John Coffey caused Percy to go catatonic after shooting "Wild Bill" Wharton.
In the film, he is portrayed by Michael Jeter.
