Several law enforcement agencies are working together to track down non-compliant sex offenders in Kentucky.
They're planning to run sex offender checks in every Kentucky county.
Their efforts began in Madison County.
On Thursday, the Richmond Police Department, Berea Police Department, Kentucky's Probation and Parole Department, the Commonwealth's Attorney, Kentucky State Police, and U.S. Marshals released information about their recent round up in Madison County.
Together, the agencies checked on the 64 sex offenders living in the county.
Out of those 64, investigators say four of them were not complying with sex offender rules.
Police arrested three of those people, but they're still looking for a fourth person, Allen Jerome Bradley, who last lived in Richmond.
