A recent report by the Missouri State Auditor’s office released on Monday indicated that local authorities in Missouri do not know the locations of more than 1,200 sex offenders, including nearly 800 who would be classified as the most dangerous.

Missouri law requires those convicted or found guilty of sexual offenses to register their name, address and other information with local law enforcement. That information is made public through a database and website maintained by the Missouri State Highway Patrol.

Missouri State Auditor Nicole Galloway said because of local official's inadequate enforcement of registration requirements, 1,259 registered sex offenders failed to follow the law. The audit found that at least 794 of the 1,259 offenders committed offenses including rape, sodomy or child molestation.

It is a felony if a sex offender fails to comply with registration requirements, but the audit showed that less than 10 percent of non-compliant offenders had an active arrest warrant.

“Law enforcement can’t track the location of registered sex offenders if sex offender laws are not enforced,” Galloway said in a statement. “This also takes away the ability of Missourians to effectively use the sex offender registry when making decisions to protect themselves and their families.”
