For a long time, Birger continued his criminal career without being convicted with any crime. He would set up his rivals to publicly threaten him so he could claim self-defense.
However, stories began circulating that State Trooper Lory Price and Birger were involved in stealing cars. Charlie was supposed to have hid them and then Trooper Price would act as though he found the cars and collected the reward, splitting it with Birger.
But the trooper and his wife soon disappeared. Birger was said to have shot the trooper while his men kidnapped and shot his wife and threw the body down an abandoned mine shaft.
When the story broke five months later, coal miners searched the mine shaft and found Price's wife. Although the trooper was considered a gangster, the killing of his wife and the way her body was disposed of was not tolerated by the people in the community. They no longer admired Charlie Birger despite his generosity.
Not long afterwards, in Franklin Country, Joe Adams was elected mayor of West City, near Benton. The new mayor aligned himself to the Sheltons and became an enemy of Charlie Birger. On December 12, 1926, two of Birger's men knocked on Adams' door and shot him in front of his wife and young daughter.
The sheriff charged Birger with ordering the mayor’s killing after the actual killers turned state’s evidence. Birger had been arrested many times, but he was charged in Franklin County, which he didn't control like Williamson County. The two killers got life imprisonment and Birger was sentenced to death.
