When S.C. Johnson scion Curt Johnson was first charged with repeated sexual assault of a child in 2011, he faced a prison term of up to 40 years if convicted.
Later, when it was revealed that the girl in question was Johnson's stepdaughter, the Racine, Wisc. District Attorney's office filed to amend his initial felony charges to include incest.
On Friday, after three years of pre-trial litigation, the cleaning products heir -- worth $3 billion -- was sentenced instead to four months in jail and a $6,000 fine.
Johnson entered guilty pleas to two drastically reduced misdemeanor charges of fourth-degree sexual assault and disorderly conduct.
Had the case made it to trial, there was a mounting feeling among residents of the Johnson family's hometown of Racine that the 59-year-old would walk.
The prosecution saw their case weaken when Johnson's stepdaughter refused to testify or turn her medical records over to the court.
The billionaire was accused of molesting his teen stepdaughter for three years, when she was between the ages of 12 and 15.
He is said to have implicated himself in these crimes by confessing to his therapist in Arizona. That treatment center refused to turn over their records, further hampering the prosecution's efforts.
"Judicial decisions and witness issues pretty much left prosecutors with nothing," said a source close to the trial. "Johnson agreed to the drastically reduced plea deal, even though there wouldn't have been much evidence they could bring in at a trial."
