Convicted Sex Offender Enters Not Guilty Plea On Assault Charges Of Cellmate

(Waupun) A convicted sex offender who is accused of assaulting his cellmate at the Dodge Correctional Institution in Waupun was arraigned Wednesday. Donald Coughlin, who is currently incarcerated at the Wisconsin Secure Program Facility in Boscobel, entered a not guilty plea to two felony counts of Second Degree Sexual Assault with Use of Force and Second Degree Sexual Assault of an Unconscious Victim. Both charges carry a Repeater enhancer. In March of 2018, a Dodge County Sheriff’s detective was asked to investigate a reported sexual assault at the prison. The victim allegedly told authorities that Coughlin made inappropriate contact with him soon after the two were locked in their cell and again while he was sleeping. When questioned, Coughlin denied any and all contact and said that nothing happened. Sexual assault tests of the victim reportedly confirmed the presence of Coughlin’s DNA. In 2017, Coughlin was convicted on numerous counts of First and Second Degree Sexual Assault of a Child in Juneau County and was sentenced to 48 years in prison. If convicted on the newer charges, the 63-year-old could face up to an additional 80 years in prison.
