North Carolina relies on electronic monitoring to keep track of thousands of offenders after they are released from prison. Through the Department of Public Safety, the state contracts with a company that uses GPS technology to track offenders' movements and ensure they are complying with release conditions.
—THE LAW: All types of offenders in North Carolina are eligible for electronic monitoring, but many are sex offenders. If the courts determine that an offender is a "predator," or if the crime involved the rape of a child, offenders are required to be on satellite based monitoring for a period that extends beyond the term of their supervision.
—HOW MANY: As of June 30, the state Department of Public Safety was tracking 2,360 offenders using GPS monitoring provided by BI Inc. That figure has gone up since last year, when there were about 875 active offenders being tracked.
—KEEPING UP: About 1,700 law enforcement officers across North Carolina constantly monitor offenders' tracking devices and respond to so-called "tamper" alerts or other issues around-the-clock. Most alerts are minor concerns or equipment problems. When a violation is suspected, field agents do home visits to find the offenders and figure out the source of the alert.
