After ending his employment with Chisum, Evans ventured to both Las Cruces and La Mesilla, New Mexico, where he became associated with John Kinney.

The outlaws lost the fight and left, only to return and open fire on the saloon which resulted in several persons killed and wounded.

A short time after that night, while Kinney was still healing, Evans and gang member Samual Blanton shot and killed Quirino Fletcher in Las Cruces, for reasons still not known.

Evans would figure prominently into the range war, often taking the lead on operations against the Lincoln County Regulators.

The Regulators reacted by tracking down Manuel Segovia, the Seven Rivers gang member believed responsible for the death of McNab, killing him.

After the Lincoln War ended, Evans and gang member Billy Campbell on February 18, 1879, killed an attorney named Huston Chapman, who was the lawyer hired by Susan McSween on behalf of her husband Alexander McSween, who was killed during the Battle of Lincoln, and the gang was again on the run from lawmen.

[citation needed] In 1948, a probate investigator from St. Louis, Missouri, William V. Morrison, located an elderly man called Joe Hines in Florida, who had claimed the lands of his deceased brother.

During Morrison's interview, Hines said that of those involved in the Lincoln County War in New Mexico, three, including himself, remained alive, and that the other two were Jim McDaniels (an Evans Gang member) and Billy the Kid.

Hines told Morrison of his experiences in the range war and surprised him by claiming that Billy the Kid was still alive, but refused to reveal the name he had assumed or exactly where he was living.

Morrison also attempted to track down former Evans Gang member Jim McDaniels, locating him in Round Rock, Texas.

The character is aligned with the Murphy/Dolan faction and is shot dead by Billy the Kid when trying to escape in the aftermath of the Battle of Lincoln.

In Battle of the Mountain Man, Evans is a ruthless and arrogant figure who, around the time of Tunstanll's death, leads a gang of rustlers who attack Jensen while he is delivering beef to John Chisum.
