DES MOINES, Iowa [KCCI]— A Des Moines man who was convicted of abusing his infant son more than a decade ago was taken into custody Thursday for allegedly violating his parole. Jonas Neiderbach, 34, was found guilty in 2011 of abusing his six-week-old son in 2009. The infant suffered brain trauma, a broken arm and broken ribs.

Neiderbach was convicted of six counts of child endangerment, but in 2013, the Iowa Supreme Court threw out two of the convictions. He was sentenced to up to 50 years in prison, with no mandatory minimum. According to the Iowa Department of Corrections, Neiderbach was released on parole in 2022. New court documents say he violated his parole at least seven times in the last six weeks. His next court date has not been set.
