- "And I-- and I saw his face, his-- his eyes, his evil. Mask had slipped. And he was gonna kill me right then and there because he knew I would make sure he would never get out again. Arm bar counter for being choked from a pinned position. Aikido. I wasn't taking it for self-defense, but it saved my life. And I got to make sure he never got out again. Well, got to try. He got out. Talked to the right people who got him the right things and he broke out, but it wasn't to escape. Crighton Dallas Wilton went to my home and killed my wife, my daughter, and my son. He walked down the street to the police station around the corner covered in their blood. He surrendered. Said the only reason he broke out was to destroy my life."
- —Eastman describing Crighton Dallas Wilton to Morgan[src]
Although Crighton Dallas Wilton never appeared onscreen, he was well described by Eastman as being a pure psychopath who was truly evil. As common with psychopaths, he was extremely charming and manipulative and also highly intelligent. Despite being a model prisoner, Crighton most likely had a strong desire to be freed from prison once again and put up a strong facade as a good person in order to achieve it. After being denied parole by Eastman, a furious Crighton was able to break out of prison not to escape, but just to destroy Eastman's life as revenge. He was proven to be a remorseless, cold-blooded murderer and slaughtered Eastman's entire family and then returned himself to prison. As a result of this incident, Crighton met his own well deserved death at the hand of Eastman, who captured him and locked him in a cell in his cabin and starved him to death.
Crighton lived somewhere in Georgia before the apocalypse began. At some point in his life, he committed numerous crimes, likely murder, which were apparently "truly unspeakable" and was imprisoned. During his imprisonment, he used his superficial charm to convince the authorities that he was making progress, in attempt to get himself paroled. Ten years later, he was up for parole and was being psychologically evaluated by Eastman which would determine his case for parole. During these evaluations, Eastman saw through his façade and recognized him for the evil psychopath that he truly was, and deemed him unsuitable for release. Realizing that his deceit had been seen through, he assaulted Eastman and attempted to murder him during one of his visits to the prison. Eastman was successfully able to repel him thanks to his Aikido training, and as a result of the incident and Eastman's psychological evaluation, Crighton was denied parole.
Some time later, Crighton successfully escaped from prison after talking to the right people and getting the necessary supplies. Following his escape, he tracked down and murdered Eastman's wife, son and daughter in an act of cold blooded revenge. Immediately after the crime, he surrendered himself to the police, claiming that he only escaped so as to destroy Eastman's life. Somehow managing to avoid a death sentence, he was imprisoned again and allocated for penal laboring in a plot of land next to state route 85. Stricken with grief and a lust for revenge, Eastman located Crighton and kidnapped him, then locked him in a cell inside a cabin built by Eastman and his late wife. There, Eastman kept him locked in the cell for the remainder of his life, and he eventually starved to death 47 days later.
He was mentioned by Eastman during his recitation of his own story. At first, Eastman avoided admitting that he killed Crighton, emphasizing that he had some to consider all life precious. Later, after Eastman is bitten and when he was burying dispatched walkers, Morgan went to help him and noticed Crighton's grave, and Eastman revealed that he went through with his plan to starve Crighton to death.
This list shows the victims Crighton has killed:
- Eastman's wife (Pre-Apocalypse)
- Eastman's son (Pre-Apocalypse)
- Eastman's daughter (Pre-Apocalypse)
- Possibly unnamed people
- Eastman (Caused)
Having murdered his family, Crighton Dallas Wilton was captured by Eastman and imprisoned in a small cell in a cabin, deep in the forest of the Georgia countryside. Denied food by his grief stricken and vengeful captor, Wilton survived 47 days before starving to death.
- If Crighton Dallas Wilton was first imprisoned for murder, he would be considered a serial killer, defined as killing at least three people within a 30 day span.
