(KNZA)--A Hiawatha man facing a pair of child sex charges will undergo a competency evaluation.

Brown County District Judge John Weingart Tuesday granted a motion filed by the attorney for 30-year-old Robert Edwardson for the evaluation, which is to be conducted by KANZA Mental Health.

A preliminary hearing in the case, which had been set for Wednesday, was placed on hold pending the outcome of the evaluation.

Edwardson was arrested last week on a Brown County warrant for two counts of aggravated indecent liberties with a child.

That followed an investigation by the Hiawatha Police Department.

Brown County Attorney Kevin Hill says the charges involve two separate victims, one between the ages of  14 and 16 and the other under 14.

Edwardson remains in the Brown County Jail on a $75,000 bond.
