This article is littered with spoilers, so I reckon you might ought'a mosey on down the road if you don't want to read any plot details.
Deek is first encountered in the mission "Spare the Rod, Spoil the Bandit". He is also mentioned in "Exhuming and Other Fine Hobbies". He is situated along with Williamson on the escarpment, holding a gun on John Marston and Marshal Leigh Johnson's posse. Deek then leads the assault immediately after this encounter. Deek survives, having only minor wounds, and is arrested by Johnson.
Johnson intends to interrogate Deek and exploit him to assist Marston's planned assault on Fort Mercer. Several days after his capture, the Williamson gang kidnaps Bonnie MacFarlane from Hennigan's Stead, and holds her under threat of execution. A Williamson gang member rides to Armadillo to deliver the ultimatum to Johnson, initiating the mission "Hanging Bonnie MacFarlane".
Johnson pragmatically accepts the exchange, carrying a restrained Deek to Tumbleweed alongside Marston, Eli and Jonah. The gang members, awaiting their arrival, ambush them during the exchange. Ironically, Deek is promptly killed by his own gang which he swore by in the cross fire. His death is announced in the Blackwater Ledger, which notes his age at time of death as 34.

- Oddly, when Jonah captures him in Spare the Rod, Spoil the Bandit he does not have his hat on. In Hanging Bonnie MacFarlane, he has his hat on. This most likely a developer oversight.
