Convicted sex offender living in duplex owned by Brown Co. sheriff

A 43-year-old convicted sex offender living in a duplex owned by Brown County Sheriff Dennis Kocken is accused of sexually assaulting a 15-year-old runaway, the Green Bay Press-Gazette has learned.  Christopher Streckenbach, of Green Bay is facing two counts of second-degree sexual assault of a child and eight counts of photographing a minor without consent as a registered sex offender.  Ashwaubenon Public Safety officers spotted the girl — a known runaway — at Bay Park Square mall on Jan. 2. Streckenback was with her at the mall, but left before officers could talk to him.  The girl later told investigators she met Streckenbach after placing an escort ad in a local entertainment newspaper. She said she was with him seven or eight times and was at his house three or four times, according to court records.  The girl said the two touched each other in a sexual manner, but did not have sex, the criminal complaint said.  She said he paid her for the sexual encounters and offered to pay her more to spend the night, according to the affidavit filed with the warrant to search Streckenbach's home.  Ashwaubenon Public Safety officers found photos of the 15-year-old runaway on a disposable camera as well as sex toys and 34 photos of naked young women, according to the inventory from the Jan. 4 search.  he duplex — in the 1300 block of Dousman Street — had been rented to Streckenbach for about two years, Kocken said Monday. That means Streckenbach was exempt from Green Bay's sex offender registry law restricting where sex offenders can live in the city.  "If I had known that Chris Streckenbach was doing something illegal, I would have arrested him myself," Kocken said.  Kocken said he knew Streckenbach had a criminal record when he rented the duplex. Kocken said he worked closely with Streckenbach's probation agent and corrections supervisors and talked to Streckenbach regularly.  Kocken said Ashwaubenon officers told him about the situation, and he accompanied them when they served the warrant.  Officers used Kocken's handcuffs to detain Streckenbach, the sheriff said.  Streckenbach was sentenced to two years prison in June 2002 for sexually assaulting a 14-year-old girl on Halloween 2001.  He is due back in court on the current charges on Friday.
