A Waupun prison inmate has been convicted of expelling bodily substances on correctional officers. A Dodge County jury has found 27 year old Cody Cromwell guilty of five counts of assault by prisoners as a habitual criminal. Cromwell claimed that he suffered from a mental illness, but a psychiatrist testified during the trial that he believed Cromwell was feigning his symptoms. The jury returned the guilty verdict and finding of no mental illness in less than 20 minutes. A sentencing hearing will be held at a later date. The charges carry a maximum penalty of nearly 40 years in prison.
