State Police are reminding all registered sex offenders that the 15-day address verification period started on Wednesday and runs through mid-month. During this period, state law requires all registered offenders to report in person to their local law enforcement agency, sheriff’s office or nearest MSP post to verify their address. The Michigan Sex Offenders Registration Act requires Tier 1 offenders to verify their address annually, during beginning of January. Tier 2 offenders must verify their address semi-annually, during the beginning of January and July. Tier 3 offenders must verify their address quarterly, during the beginning of January, April, July and October. Failure to do so carries a penalty of up to two years of incarceration. All registered sex offenders must also report a change of name, address or other important information. Failure to do so is a four-year felony.
