Fond du Lac City
Police Department
SEX OFFENDER
INFORMATION BULLETIN
PREPARED BY: Chief Duane Johnson
The Fond du
Lac Police Department is releasing
the following information pursuant to Wisconsin State Statute 301.45 and 301.46
(Act 440), which authorizes law enforcement agencies to inform the public of a
sex offenders release when, in the discretion of the agency, the release of
information will enhance public safety and protection.
The
individual who appears on this notification has been convicted of a sex offense
that requires registration with the local law enforcement agencies. Further, their previous criminal history
places them in a classification level which reflects the potential to
re-offend.
This sex
offender has served the sentence imposed on him by the courts and has
advised officials that he/she will be living in the location below. THIS PERSON IS NOT WANTED BY THE POLICE AT
THIS TIME. THIS NOTIFICATION IS NOT INTENDED TO INCREASE FEAR; RATHER, IT
IS OUR BELIEF THAT AN INFORMED PUBLIC IS A SAFER PUBLIC.
Sex
offenders have always lived in our communities but it was not until passage of
Act 440 (which mandates sex offender registration) that law enforcement even
knew where they were living. In many
cases, law enforcement is now able to share that information with you. Citizen abuse of this information to
threaten, intimidate, or harass registered sex offenders will not be
tolerated. Further, such abuse could
potentially end law enforcement’s ability to do community notification. We believe the only person who wins if
community notification ends it the sex offender, since sex offenders derive
their power through secrecy.
The Fond du
Lac Police Department is available to help you set up Neighborhood Watches and to
provide you with useful information on personal safety. The Fond du Lac Police Department can be
reached at 322-3700. If you have information regarding current
criminal activity of this or any other offender, please call 906-5555. In the case of an emergency, call 911.
