The county has a total of 70 registered sex offenders, 15 of them are incarcerated and the remaining 55 live within the community.
According to Deputy U.S. Marshall Richard Upchurch, six of the 55 were found non-compliant and a warrant has been issued for each of their arrests.
"We've been doing it all across north Mississippi. We also did a roundup in Coahoma and Tallahatchie (counties)," said Upchurch.
Sex offenders are required to re-register every 90 days and get an identification card.
First time sex offenders are required to report to their local sheriff’s department and to visit the Highway Patrol Station for their identification card.
The sheriff’s department verifies addresses by making home visits.
"We have more man power, so we often come and help the sheriff’s department. It usually takes between four to five hours," said Upchurch.
If a sex offender changes jobs or residences, he is required to report to their local highway patrol station within 90 days.
"It's all about communication," said Upchurch.
Previously, offenders were required to live at least 1,500 feet away from schools, but as of July 1, offenders are required to live at least 3,000 feet away.
"There are some ways that doesn't apply. If the sex offender has been living at an address and the county decides to build a school in or near that area, then the sex offender is not required to leave," said Upchurch.
"We really appreciate the U.S. Marshalls for assisting us with the sex offender verification,” said Sheriff Kelvin Williams.
"In conjunction with the U.S. Marshalls, we just want to let the citizens of Bolivar County know that they are safe and that we are monitoring sex offenders.
"We will make sure that every sex offender will remain in compliance. The law is the law and we are not going to circumvent from it," said Williams.
