Eli is one of Marshal Johnson's deputies, and is the spotter of Bollard Twins Gang in the second mission that the Marshal gives John. Eli is overweight, possesses a lazy-eye and a strong Southern accent.
Eli is competent with a weapon, as demonstrated in his missions alongside John Marston. Eli has also demonstrated competence in policing duties, being the one to spot the Bollard Twins Gang in Pike's Basin. He is also very strong, getting one of Bill Williamson's men to talk with just one punch to the chest. Eli's dedication to his job and his honesty despite his awkwardness makes him an unlikely asset to the Marshal - these are qualities in short supply in Armadillo.
Eli appears in the side-mission"Dinner For Two". Marshal Johnson explains that he sent Jonah and Eli out into town, likely to watch over the survivors. Unfortunately, it would seem Eli became infected before turning on Jonah, devouring him.
He and the other deputy, Jonah, are very contrasting in appearance and personality. Eli wears light clothes, while Jonah wears dark clothes. Jonah has a lot of hair while Eli has almost none, Jonah is skinny while Eli is overweight. Personality-wise, Eli appears to be hard-working and friendly, while Jonah is lazy and rude.
During cutscenes, Eli walks with a limp, but in gameplay he walks normally, with the default action of NPCs.
Despite calling Nigel West Dickens by his name in earlier missions, Eli repeatedly referes to him merely as "the Snake oil guy" in "The Assault on Fort Mercer". This may be due to Marshal Johnson's ridicule when Eli tried defending West Dickens' tonics to him earlier.
During Undead Nightmare, hogtying and picking him up may result in a glitch occurring, which does not allow the player to put him down.
