A Kansas man was sentenced Thursday to life in prison without the possibility of parole for 25 years after being convicted of child sex crimes.

The Kansas Attorney’s Office said Douglas D. Peterman, 44, of Hanston, was found guilty in October by a Hodgeman County jury of three counts of aggravated indecent liberties with a child.

The crimes were committed between August 2010 and April 2012. The charges stemmed from an investigation by the Dodge City Police Department, Hodgeman County Sheriff’s Office and the Kansas Department for Children and Families.
