This is not your average house call. In fact, in this case, if you answer the door, you're most likely in a bit of trouble.
"Today they're going out and checking 35 targets in the tri-county area," Sgt. Kevin Mark of the Michigan State Police said of all local police agencies. "What they're looking for is sex offenders who have not verified."
By law, if you've been convicted of a sex crime and put on the sex offender registry, you have to verify your home address with local police, once a year for a misdemeanor crime, four times a year for a felony.
Tuesday was day one of a two-week state-wide sex offender sweep by the Michigan State Police, looking for those who didn't follow the rules.
"The fact is we're going to hold them accountable," Sgt. Mark said.
News Ten went along with Eaton County Sheriffs Deputies Tuesday as they searched for six such sex offenders, but each and every address they tried was the same story.
"The gentleman we tried to contact at this address, we're pretty sure he doesn't live here anymore," Deputy Brian Thomas said. "We're going to use some search engines back at the station to try to locate another address for him."
When the police find who they're looking for, it will be up to their discretion whether or not they send these people to jail. What's most important, the police said, is that everyone follows the rules, and most do.
"Overall we have a 92 percent compliance rate in this state," Sgt. Mark said. "In the tri-county area, it's at 93 percent."
But for those who choose to violate their probation, police said, they will find you and hold you accountable.
The state police conducted a similar sweep back in February. Then, the sweep checked 1,500 sex offenders in Michigan, resulting in 179 arrests and 248 requests for arrest warrants.
