Sex Offender Press Release


Placement of Sex Offender

Date: April 25, 2022

Type: Placement of Sex Offender 

Released by: Chief Raymond Clark

Contact Person: Captain Stefanie Adams – 262-728-8787 Ext 105

Narrative: The following is a press release authorized by a core team made up  of representatives from local law enforcement, Wisconsin Department of Health Services and Department of Corrections.  The core team evaluates and makes decisions on the level of notification to the community for the pending release of sex offenders under Wisconsin Statute 301.46 (Act 440).  Community notification furthers the interest of public safety and it is our belief that a better-informed public is a safer public.   The Town of Delavan Police Department is releasing the following information pursuant to Wisconsin Statute 301.46(Act 440) which authorizes law enforcement agencies to inform the public of a sex offenders release when that information will enhance public safety, awareness, and protection. The individual who appears on this notification has been convicted of a sex offense. He is not wanted.  

Anthony R. Teifke age 30 was convicted of First Degree Sexual Assault of a Child and Possession of Child Pornography.  Teifke’s victim was a minor known to him.  As of May 3rd, 2022 Teifke will be residing at 6436 Mound Rd. Delavan, WI.  

Teifke is a lifetime registrant of the Wisconsin Sex Offender Registry and will not be allowed to leave the residence unsupervised. Teifke is also required to participate in, global positioning satellite tracking and is subject to frequent, unannounced, random home visits by the Department of Corrections. 

Citizen abuse of this information to threaten, intimidate, or harass registered sex offenders will not be tolerated.  Further, such abuse could subject those who commit such acts to criminal penalties, and potentially end law enforcement’s ability to conduct community notification.  We believe the only person who wins if community notification ends is the sex offender, since sex offenders derive their power through secrecy.
