An accomplished Michigan sex predator is finally behind bars.
27-year-old Jamie Van Klaveren faces several charges of criminal sexual conduct.
Police says he used a younger relative to lure children into his Kentwood home, just outside of Grand Rapids.
The alleged abuse happened during sleep overs.
Police say Van Klaveren even used sleeping pills on some of the victims.
13-year old relative tipped police off after suffering years of abuse.
"I have to say that the original victim in this case is the one that was so courageous to come forward and say you know, enough is enough. I need help. This has got to stop," says, Lt. Paul Robinson Wyoming Police Department.
Police say they know of at least 14 victims.
There could be more and they are continuing their investigation.
