A criminal complaint has been issued in Waupaca County Circuit Court against a Waupaca man, who faces five felony sex-related charges. 33 year old Matthew W. Alexander, a current inmate at the Oshkosh Correctional Facility, is charged with two counts of 2nd degree sexual assault of a child, plus single counts of child enticement, exposing genitals to a child, and possession of child pornography. The complaint alleges Alexander had sexual contact with a 13 year old in March and April of 2017 in Waupaca. Police also allegedly found dozens of photos of child pornography on his phone. Alexander is currently serving a 3-year prison term, after his probation was revoked in 2017, following a conviction in 2015 for intimidation of a victim with threat of force. If convicted on the current charges, he could face up to 130 years in prison. Alexander is due in Waupaca County Court August 21st.
