(KAIR)--A decade-long child sex-crimes case, dating back to late 2014 in Atchison County, concludes with an Atchison man going to prison for the rest of his life.

That's the fate of Austin Kau, sentenced earlier this month in Atchison County District Court to life in prison without the possibility of parole until after 40-years are served.

Kau, Atchison County Attorney Sheri Becker says in a release, was sentenced for the crime of aggravated criminal sodomy, a crime brought to the attention of Atchison Police in 2014, with the report alleging Kau had sexually assaulted his 4-year-old son. However, during that same time, Buchanan County, Missouri authorities received a report that Kau had, in their jurisdiction, engaged in inappropriate conduct with a 6-year-old child.

Although charges were filed against the now 43-year-old Kau in Atchison County, Becker says he entered a plea to the Missouri crime of sexual exploitation of a child, landing him in a Missouri prison; however, once released, Atchison Count litigation began; and following a jury finding him guilty of the Atchison County crime in April, 2024 Kau later contested his sentencing, leading to a new attorney and ultimately to this month's life prison sentence.
