- "Phelps, I thought you were under suspension? I've got nothing to say to a bum like you."
- ―Worrell, regarding Phelps' suspension following the scandal
Although Chief of Los Angeles Police Force, Worrell was ultimately corrupt. He collaborated with the Mayor Fletcher Bowron, District Attorney Donald Sandler and several other important individuals in the Suburban Redevelopment Fund. Worrell contributed investment money into the development of new houses for returning G.I.s. However, the true intent of the group was to scam millions of dollars from the government. The plan was spearheaded by Leland Monroe. Worrell provided support using his status and authority as Police Chief to cover their illegal activities and corruption.
Events of L.A. Noire
Worrell met with Bowron, Sandler and Raymond Gordon to discuss the Vice department's scandal, involving a prostitute known as "Brenda". Unfortunately, their options were limited, and would consequently expose police corruption to the public and generate negative press. However, a solution was offered by Vice Detective Roy Earle. Earle offered another story for them to give to press to distract the public from their corruption, but in exchange to be part of their syndicate. Earle revealed to them Cole Phelps's extra-martial affair with Elsa Lichtmann. As Phelps was trying to close the stolen morphine case, he questioned Courtney Sheldon and Dr. Harlan Fontaine (who was also part of the SRF). Worrell appeared and interrupted Phelps' investigation, summoning him to his office where he revealed the adultery charges against him. Worrell suspended Phelps from the force, taking his gun, badge and harshly chastised him. Ironically, Worrell's intervention also protected Fontaine and Sheldon from being discovered as part of the stolen morphine distribution.
- "I hope this had nothing to do with your seditious pinko friends, Phelps. Get me answers, Detective."
- ―Worrell, concerning the explosion
Worrell appeared at the remains of the Nicholson Electroplating Plant. However, even while demoted into the lowly arson squad, Phelps was able to uncover indications of Leland Monroe's conspiracy as well as Worrell's connection to it. The efforts of Phelps and Jack Kelso ultimately undid the SRF's plans and threatened to expose Worrell's involvement and corruption. To prevent this, Worrell sent the entire force out to apprehend Kelso in order to silence him. Worrell was finally confronted by Leonard Petersen who sided with Kelso and Phelps. He warned Worrell that the conspiracy would be exposed, but gave him a chance to bargain his way out. It would appear that Borwon and Worrell were able to make a deal with Petersen, by securing him position as new district attorney, in exchange for keeping their corruption a secret. With his position secure, Worrell made a final appearance at Phelps' funeral.
