(KMOV.com) -- St. Charles County Police continue the investigation into a convicted sex offender who is accused of drugging and raping another young girl Thursday.
Authorities charged 47-year-old William Thomas Wilburn with statutory sodomy, statutory rape and enticement of a child.
Police said Wilburn had previous convictions for statutory rape and statutory sodomy back in February 2006, but was able to avoid major prison time.
“We have reason to believe there are other victims out there for sure,” said St. Charles County Prosecuting Attorney Tim Lohmar, “Who they are, how many there are – we don’t know yet.”
A local child advocacy group, Grandparents and Others on Watch, said the system to prosecute sex offenders is failing children. Executive Director Dan Peek said Wilburn should have gone to jail the first time he was convicted instead of being able to find another alleged victim.
“The justice system does not view child molestation as a serious crime,” Peek said, “It’s considered a minor infraction.”
Peek said he believes the parole system is weak and allows sex offenders to slip through the cracks.
“It’s not the court. It’s not the Department of Corrections,” said Peek, “It’s the probation and parole people.”
