Mark Chamberlain is being held with no bond.

While all sex offenders must register with the state, repeat offenders do not receive any extra monitoring. They do have to have their addresses verified every 3 months, instead of the standard 6 month requirement.

Two deputies work the sex offender registry in Guilford County. They manage registration for nearly 900 offenders. When they have time and help they also perform random checks.

"Ride their addresses, make sure that they're where they say they live or where they say they work 52:40 given the manpower we have on a full time basis, we do utilize our school resource officers on their breaks, and sometimes a bailiffs officers will come over when there is a judge's conference or something so we can do a widespread check," said Corproal Matt Suits, Guilford County Sheriff's Office.

As for Mark Chamberlain, the last time his address was verified was August 10. He wears an electronic monitoring device as part of his conditions of his release from prison.

Chamberlain was convicted of Second Degree Rape twice and once for Assault With Intent to Commit Rape back in the 1970s.

He's proven to be a repeat offender and according to government research, as many as 25-percent of offenders will do it again.

This case had a lot of people asking on WFMY News 2's social media pages - can sex offenders be rehabilitated?

The state prison system is certainly trying. Its using a program called SOAR for inmates who have committed multiple sex crimes. SOAR stands for Sex Offender Accountability and Responsibility Program.

2 Wants to Know visited the program last year and learned that out of 100 inmates who take the course, only 8 are reconvicted. The study found out, out of 100 inmates who do not take the course, 37 are reconvicted within 3 years.
