Josefa Johnson, the sister of Lyndon B. Johnson, was born in 1912. She was a student at San Marcos and after marrying early was divorced in 1937. Three years later she married Williard White, a lieutenant colonel in the United States Army. The marriage ended in divorce in 1945.
Josefa took a keen interest in politics and helped her brother in his successful 1948 senatorial campaign. In 1955 she married James B. Moss. She had a reputation for wild behaviour and was said to work for Hattie Valdez's private club. Josefa was also an alcoholic and was admitted to hospital several times with health problems.
It was rumoured that Josefa Johnson had affairs with John Kinser and Mac Wallace. Kinser opened a golf course in Austin. According to Barr McClellan, the author of Blood, Money & Power: How LBJ Killed JFK, Kinser asked Josefa if she could arrange for her brother to loan him some money. Johnson interpreted this as a blackmail threat (Josefa had told Kinser about some of her brother's corrupt activities).
On 22nd October, 1951, Mac Wallace went to Kinser's miniature golf course. After finding Kinser in his golf shop, he shot him several times before escaping in his station wagon. A customer at the golf course had heard the shooting and managed to make a note of Wallace's license plate. The local police force was able to use this information to arrest Wallace.
Wallace was charged with murder but was released on bail after Edward Clark arranged for two of Johnson's financial supporters, M. E. Ruby and Bill Carroll, to post bonds on behalf of the defendant. Johnson's attorney, John Cofer, also agreed to represent Wallace.
On 1st February, 1952, Wallace resigned from his government job in order to distance himself from Lyndon B. Johnson. His trial began seventeen days later. Wallace did not testify. Cofer admitted his client's guilt but claimed it was an act of revenge as Kinser had been sleeping with Wallace's wife.
The jury found Wallace guilty of "murder with malice afore-thought". Eleven of the jurors were for the death penalty. The twelfth argued for life imprisonment. Judge Charles O. Betts overruled the jury and announced a sentence of five years imprisonment. He suspended the sentence and Wallace was immediately freed.
According to Bill Adler of The Texas Observer, several of the jurors telephoned John Kinser's parents to apologize for agreeing to a "suspended sentence, but said they did so only because threats had been made against their families."
Josefa Johnson died of a cerebral hemorrhage on 25th December, 1961.Despite state law, no autopsy was conducted. Twenty-three years later the lawyer, Douglas Caddy, wrote to Stephen S. Trott at the U. S. Department of Justice. In the letter Caddy claimed that Billie Sol Estes, Lyndon B. Johnson, Mac Wallace and Cliff Carter had been involved in the murders of several people including Josefa Johnson and John Kinser.
