TREYNOR, Iowa (AP) – State officials have suspended the license of the Treynor schools superintendent for 30 days, saying he should not have let his son work unsupervised as a custodian for the district after the boy was accused of inappropriate sexual conduct. The Board of Educational Examiners also ruled last week that a letter of reprimand would be given to Superintendent Kevin Elwood.

Elwood was accused of two violations of Iowa Educational Code, including failing to make reasonable efforts to protect the health and safety of students. His attorney didn’t return a call Tuesday.

In September 2013 Elwood’s son, Kreighton Elwood, pleaded guilty to two counts of assault and one of false imprisonment. He was sentenced to 14 days in jail, two years of probation and ordered to register as a sex offender.
