U.S. Marshals and police say they're focused on making sure people who committed sex crimes are behaving once they get out of prison.
That was the purpose behind a recent door to door check of sex offenders in southern Kentucky.
Out of 316 sex offender compliance checks for Operation Cumberland Valley, police say more than 30 sex offenders were found to be non-compliant, and four are now considered fugitives.
Operation Cumberland Valley took place on August 30 and 31, and involved U.S. Marshals and police from seven counties, including Pulaski and Laurel.
During a news conference Tuesday to announce the results, federal officials said more than 20 sex offenders were non-compliant, one was found with weapons, one turned out to be a fugitive wanted out of Indiana, and several were actually in jail on other crimes.
Officials say they still couldn't find four other sex offenders, who are now considered fugitives.
"The four.. two are move-ins from other states," Calvin Whitis of the U.S. Marshal's office said. "These sex offenders so many times are so mobile, they move from state to state to state."
Also this morning, officials said a large number of sex offenders from other states were found living in Kentucky.
U.S. Marshals say for whatever reason, it's easier for them to get on welfare in Kentucky than other states.
The U.S. Marshals service estimates nationwide, approximately 10 percent of registered sex offenders are non-compliant.
