2,000 sex offenders relocated all over the United States after Hurricane Katrina, and no one knows where they are.
Today's edition of US Today highlights the problem that local and national law enforcement are trying to get their hands around.
Database matches of offenders with those who applied for aid indicate that 30 states may be affected. Sex offenders are the most likely to repeat their crimes.
This site found that over a 25-year period, child molesters had higher rates of reoffense than rapists. Individuals who were rearrested using survival analysis (which takes into account the amount of time each offender has been at risk in the community), show that over longer periods of time, child molesters have a higher failure rate—thus, a higher rate of rearrest—than rapists (52 percent versus 39 percent over 25 years).
Another study shows that child molesters in Canada were reconvicted of sexual or violent crime 42% of the time.
The long term follow-up study referred to above included a control group of non-sexual criminals. The highest rate of recidivism (77%) was for those with previous sexual offences, who selected boy victims outside the family and who were never married.
In general, rapists reoffend more often than child molesters.
Among child molesters, those with male victims have been found to have the highest recidivism rates, followed by those with unrelated female victims.
Incest offenders show the lowest recidivism rates of all sexual offenders.
