Governor Doyle says more than 400 sex offenders who eluded the state's registration law were found since a new initiative was launched five months ago.
Doyle says now 88 percent of all sex offenders are registered with the state.
The governor also says the state is creating a "Wisconsin's Most Wanted" list of the most dangerous sex offenders who have failed to register.
The initiative Doyle set up last September is called SAFE - which stands for Sex Offender Accountability and Felony Enforcement.
The SAFE teams include retired law enforcement officers who work with corrections department registry specialists to track down sex offenders who've managed to avoid registering.
The governor says 436 sex offenders have been located since September, including 273 who committed crimes against juveniles.
