Police: Local man repeatedly used stun gun on child

A traffic stop early Wednesday ended with police arresting a man wanted on aggravated assault and neglect of two dependents.

A Marshalltown Police officer spotted Mario Castellanos, 23, of Marshalltown, driving under suspension and pulled him over at the intersection of Anson Street and Third Avenue, said Lt. Ronald Ohrt, with the MPD.

Castellanos was wanted on a warrant for a Feb. 28 incident where he allegedly assaulted his stepson on the 10 block of East Grant Street. The incident occurred in front of his son while he was caring for the two boys.

Marshalltown Police Chief Mike Tupper said Castellanos used the stun gun on the boy, and the complaints indicate that he had done so repeated over several years. The attack injured the boy, who was treated medically, but not hospitalized.

Police charged Castellanos with aggravated assault, an aggravated misdemeanor, and two counts of neglect of a dependent, a Class C felony.

Castellanos appeared in court Wednesday, where the judge issued a no-contact order on the two boys and appointed a public defender. The bond on Castellanos is set at $10,000. His preliminary hearing is scheduled for April 5.

A Class C felony is punishable by up to 10 years in prison and a fine ranging from $1,000 to $10,000.
