Trends in Sex Offender Arrest,
Conviction, Sentencing, and
: Despite the media attention to sex abuse in the Catholic Church,
internet solicitation of minors on
To Catch A Predator,
and the recent stranger abduction
/assault cases involving Elizabeth Smart and Jaycee Lee
, sex crime has been on
the decline over the past two decades, mirroring the overall decline in violence in this
country since the early 90’s.
Sex Crime Locations
: About 40% of sexual assaults take place in the victim’s own home,
and 20% take place in the home of a friend, neighbor or relative (Bureau of Justice
Arrests and Prosecution
: New categories of sex defendants are entering our federal and
state court systems, due to new laws , while new Federal, state, and local law enforcement
initiatives appear to have increased both sex crime reporting and clearance rates.
: Compared to a decade ago, Sentences for convicted sex offenders are now
more likely to include incarceration, but the majority(60%) of all convicted sex offenders
are currently in the community corrections system.
: Sex Offenders are not a homogeneous group in terms of recidivism risk,
but overall, sex offenders pose the lowest risk of re
offending of all offender groups. The
U.S. Department of Justice found that over a three year period after being released from
prison, 5.3% of sex offenders were rearrested for a new sex crime (Bureau of Justice
The Community Control of Sex
Offenders: New Initiatives
: Legislation has been passed allowing lifetime probation
or parole supervision for convicted sex offenders in twenty six states; in these
jurisdictions, GPS monitoring of offender location and movement is also the
New Classification and Reporting Procedures
: Adam Walsh Act requirements
if implemented fully
will increase the size of the registered sex offender
population, and mandate uniform offense
driven reporting requirements. To
date, only Ohio has substantially met these requirements.
Many jurisdictions have passed legislation that restricts
registered sex offenders from living near schools, parks, libraries, bus stops,
and other places where children congregate.
Monitoring the Homeless Sex Offender Population
: Due to residency
restrictions, a growing number of sex offenders are registering as homeless,
which requires new strategies for monitoring this subgroup of registered sex

Can Hot Spots Locations For
Registered Sex Offenders Be
In the Ohio illustration, it is apparent that registered
sex offenders are clustered in a small number of Ohio
No research has been conducted to date on whether
sex offenders are locating in jurisdictions where
reporting requirements and/or monitoring strategies
are more lenient.
It is also possible that registered sex offenders are
locating/ clustering in those areas without residency
restrictions for sex offenders.
Estimates of the Size of the
Sex Offender Problem
National Compliance Estimates by NCMEC: There are
100,000 sex offenders
currently not in
compliance with sex offender registration/notification
These estimates are based on telephone survey data,
which raises reliability concerns.
Compliance rates are likely to vary both within and
across states, due to a variety of factors, including
(1)resources,(2) qualifications of personnel ,(3)
monitoring frequency, and (4) access to technology.
An Overview of Our Case Study
We need to understand how compliance with sex offender
registration requirements is monitored at the state and local level.
We need to understand how investigators identify
sex offenders who are not in compliance.
: We need to understand the specific techniques,
technologies, and resources investigators use to locate missing sex
: We need to understand why sex offenders
abscond, and how missing sex offenders avoid apprehension. We are
particularly interested in the use of ID Theft and/or ID manipulation.
We need to understand the key linkages that facilitate( or
state cooperation and coordination in the
location and apprehension of missing sex offenders.

Case Study Site Selection Strategy
Three initial criteria: size, location, and innovation
Our First Site Selection Criterion:
We have conducted site visits of the three State systems
with the largest number of Registered Sex Offenders:
California, Texas, and Florida
; approximately 33% of all
registered sex offenders in the United States reside in these
We have also identified three
Oklahoma, and Hawaii
with much smaller number of
registered sex offenders to determine whether “size
matters” in terms of how sex offenders are monitored, and
the techniques used to locate missing sex offenders.

Key Findings from Initial Site Visits
The responsibility for monitoring compliance
with sex offender registration and for locating absconders
varies from state to state. There are three distinct models:
Centralized, decentralized, and Hybrid.
typically established a statewide sex
offender unit to manage compliance/ non
either a local , county, or regional responsibility of law
Systems combine features of centralization( the
registry data base and/or initial registration) and
compliance monitoring ( by local police or Task Forces)
centralized Sex Offender
Registration, Monitoring, and
In Texas, the initial registration, monitoring
compliance, and absconder location/apprehension is a
function; in some parts of the state( e.g.
Agency Task Forces have been established,
but in many areas the responsibility falls on local police
departments. The statewide sex offender registry data base
is maintained by the State Office of Public Safety.
: In California, monitoring compliance and
absconder location/apprehension is
county task forces have been established and maintained
utilizing Federal grants to support the program, including
overtime for project personnel and access to technology
designed to locate missing sex offenders.
: In Connecticut, a hybrid model is used.
There is a centralized registration process managed by
the State Police’s Sex Offender Registry Unit.
Responsibility for locating and apprehending
compliant sex offenders is generally
decentralized and left to local police agencies
throughout the state.
However, the State Police in Connecticut are involved
in location and apprehension if the sex offender’s last
known residence is in one of the towns covered by the
Finding 2:Reporting Requirements
For Registered Sex Offenders Vary
: The current requirement is one in
person address verification
per year for all registered sex offenders. For those individuals
classified as sexual predators, four verifications per year are required.
The current requirement is one address verification per year. Sex
offenders who have been civilly committed( n=1200), or transients( 1500
statewide) are required to verify address every thirty days. Sex offenders with 2
or more priors must appear every 90 days at a local police department.
All registered sex offenders must verify their residence every 90
days, via a
address verification system. In addition, they must
inform the Registry within 5 days of any changes in name, place of
employment, school, and internet identifiers.
: In Riverside County, SAFE team members conduct at least one
address verification per year, but due to contacts/
law enforcement, and/or the Sheriff’s office, it is estimated that each registered
sex offender is “seen” 2
3 times per year.
level Variation in Compliance Rates
: Variation in compliance rates identified by county( and within
county, by circuit), but overall non
compliance estimated at 5%( with
According to the Director of the Sex Offender Registration

About 8%(400) of the 5000 registered sex offenders in
Connecticut are currently listed as non

compliance rates has
been identified, with a low of 4.9% in San Diego ( with 4000

Finding 4:We did not find a Link
Between Missing Sex Offenders and
: Offenders certainly use aliases, but ID Theft is
: No evidence of ID Theft, but aliases are always
used to avoid detection during police stops.
: Offenders attempt to change appearance,
and use aliases; no cases of stolen identities.
: In a few cases, offenders left the country
and returned illegally using a “fake” identity.
: Investigators have access to a broad range of
local, state, and national data bases, including both
commercial and public agency data bases.
recent cuts in Federal grants have resulted in
fewer personnel, which translates to limitations in the
types of searches completed on available data bases.
Investigators rely on U.S. Marshal’s
Service to locate “hard to find” missing sex offenders
: Jurisdictions with active Task Forces appear
to have greater access to technology.
Finding 5:The Technology Available
to Locate Missing Sex Offenders
varies both within and across states

Review criminal history for aliases
technological “Old School”
Investigative Strategies appear to be
consistently used across jurisdictions to
Locate Missing Sex offenders
: Investigators find that even when missing sex offenders move
away to avoid detection, they move to areas where they have family ties.
In these cases, the key is knowing where relatives reside.
Investigators indicated that they “worked” these cases as fugitive
apprehension cases, beginning with interviews of family, friends,
relatives, and coordinating intelligence with the statewide fugitive
apprehension unit and, where applicable, the U.S. Marshal’s Service.
: Over half of all missing sex offenders were located last
year during grant
supported sweeps of areas where these offenders
were thought to reside.
: While new data systems are often a timesaver, it is the “old
school” techniques that result in the location of the majority of sex
offenders; most are located within three months of being officially
listed as “missing”.
Finding 7:The Role Of The U.S. Marshal
Service varied in the Four States
: active role, including Task Force participation.
to date, only a limited role, but due to resource
constraints, it is anticipated that the U.S. Marshal’s
service will be more active in the future for cases
involving out of state location and apprehension.
: moderate role, linked to hard to find
missing sex offenders; every few months, a list of active
warrants for missing sex offenders is forwarded to
limited role in Riverside County, but more
active in other parts of the state.
Issues To Consider: Final Thoughts
Centralized vs. Decentralized Sex Offender Registration,
Monitoring, Location, and Apprehension Practices
Interstate Transfer of Sex Offenders
Interstate Cooperation in the Location and Apprehension
of Missing Sex Offenders
Identity Theft and Identity Manipulation among Missing
Technological vs. Non
technological Location Strategies
Are Missing Sex Offenders Really
: Verification of residence becomes more
difficult when the offender is homeless.
compliance may be a function of clerical
errors at the local level in this decentralized system.
compliance has been linked to
in verification system gliches.
: In some parts of California, a sex offender
can move without notification and not be considered
in violation if he subsequently
agrees to re
The Absconders: Where Are They?
How do they avoid detection?
Investigators believe most absconders remain in the state, but
move to large cities, work as day laborers, do not obtain credit cards in
their name, and use multiple names during police contacts( in
particular Hispanic sex offenders).
The vast majority of missing sex offenders are located within the
state, using “old fashioned” non
technological police work( starting
with a visit to the last known address)
Investigators here believe absconders attempt to use a
variety of addresses to avoid initial detection; some will change their
physical appearance to avoid detection; others become homeless,
making them difficult to track.
: The majority of absconders in Riverside County moved
without notification to another part of the state; a small number leave
the state and a handful have left the country. In only two cases did the
offender employ identity theft to avoid detection.
