MASON CITY — The owner of a Mason City gymnastics club has pleaded not guilty to child sexual abuse charges.

53-year-old Douglas Hagenow, who is listed as the owner of Active Kids Gymnastics, was charged last month with one count of second-degree sexual abuse and two counts of third-degree sexual abuse against a child victim.

Criminal complaints filed in Cerro Gordo County District Court state that between 2009 and 2014, Hagenow committed sexual acts, with the second-degree sexual abuse charge stating with a female under the age of 12 on at least two separate occasions, and on the third-degree sexual abuse charges with a female under the age of 14.

Hagenow filed a written plea of not guilty to the charges last week in Cerro Gordo County District Court, with his trial being scheduled to start on January 25th. If convicted of all three charges, Hagenow would face up to 45 years in prison.
