    Description

    This study was conducted to evaluate and better improve inter-jurisdictional consistency and coordination of SORN (sex offender registration and notification) systems operating within the United States under SORNA (the Sex Offender Registration and Notification Act). The study examined the progress that has been made toward SORNA's goals as envisioned in 2006, with a particular emphasis on changes in information sharing over that period. The study utilized a mixed-method approach, including nationwide analyses of official data and a series of in-depth state case studies featuring interviews with 152 federal, state, and local personnel involved in various aspects of SORN operations and policy development across 10 states. Specific areas of focus included: 1) the nature, extent, and dynamics of state implementation of SORNA requirements; 2) the scope and evolution of information-sharing practices within the states, including both areas of success and challenge; and 3) the impacts of federal initiatives, including the expanded role of the US Marshal Service and information technology initiatives, on the achievement of SORNA's goals.

    Description

    In 2000, the District of Columbia City Council passed the Sex Offender Registration law. This law requires a person convicted, or found not guilty by reason of insanity, of a registration-required offense to register with the District of Columbia, provided the individual lives, works, or attends school here. Generally speaking, an offense requiring registration is a felony sexual assault (regardless of the age of the victim); an offense involving sexual abuse or exploitation of minors; or sexual abuse of wards, patients, or clients. The Court Services and Offender Supervisory Agency (CSOSA) will complete the initial registration. Other District agencies also have the responsibility to notify either CSOSA or MPD about sex offenders. These agencies include the Department of Corrections, Forensic and Mental Health Unit of St. Elizabeth's Hospital, and the District of Columbia Superior Court.

    Description

    This study examined various ways states approach and sanction sex crimes (i.e., child sexual abuse, incest, and sexual assault) and sex offenders. The aim of the study was to obtain basic information about policies and procedures of probation and parole agencies with respect to adult sex offender case management. State corrections administrators in 49 states and the District of Columbia were contacted to supply information on their states' probation and parole offices and the corresponding jurisdictions. From these offices, probation and parole supervisors at the office-management level were selected as survey respondents because of their familiarity with the day-to-day office operations. Respondents were asked about the usage of various supervision methods, such as electronic monitoring, requiring offenders on probation or parole to register with law enforcement agencies, and polygraph testing. Sanctions such as requiring the offenders to seek treatment and forbidding contact with the victim were discussed, as were various queries about the handling of the victim in the case (whether a written statement by the victim was routinely included in the offender's file, whether officers usually had contact with the victim, and whether there was a system for advising victims of status changes for the offender). Other questions focused on whether the office used specialized assessments, caseloads, programs, and policies for sex offenders that differed from those used for other offenders. Various issues regarding treatment for offenders were also examined: who chooses and pays the treatment provider, whether the agency or the court approves treatment providers, what criteria are involved in approval, and whether the office had an in-house sex offender treatment program.

The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. This study represents the first comprehensive national assessment of law enforcement uses of and perspectives on sex offender registration and notification (SORN) systems. The two-year, mixed-method study featured collection and analysis of interview data from over two-dozen jurisdictions, and administration of a nationwide survey of law enforcement professionals. The study examined ways in which law enforcement leaders, uniformed staff, and civilian staff engaged in SORN-related duties perceive SORN's roles and functions, general effectiveness, and informational utility. Additionally, the study elicited law enforcement perspectives related to promising SORN and related sex offender management practices, perceived barriers and challenges to effectiveness, and policy reform priorities. This collection includes two SPSS data files and one SPSS syntax file: "LE Qualitative Data.sav" with 55 variables and 101 cases, "LE Quantitative Data-ICPSR.sav" with 201 variables and 1402 cases and "LE Quantitative Data Syntax.sps". Qualitative data from interviews conducted with law enorcement professionals are not available at this time.

    Description

    This study examined the effects of comprehensive registration and community notification policies on rates of sexual violence in South Carolina. Specifically, it proposed to (1) evaluate whether broad sex offender registration and notification policies have reduced recidivism or deterred new sexual offenses, (2) examine whether unintended effects of broad registration and notification policies occurred, and (3) focus on the effects of registration and notification as it pertained to offenses committed by adults. The study examined whether the introduction of sex offender registration and notification laws in South Carolina were associated with reductions in sexual crimes and, if so, whether this reduction could be attributed to an actual reduction in sexual violence and/or recidivism (i.e., an intended effect) or to changes in criminal judicial processing of individuals for registry crimes (i.e., an unintended effect). Specific study aims included examining whether: (1) South Carolina registration and notification policies had the intended effect of preventing first time sexual offending; (2) South Carolina registration and notification policies had the intended effect of reducing sexual recidivism for known sex offenders; and (3) South Carolina registration and notification policies had the unintended effect of reducing the probability that individuals who committed sexual crimes would be prosecuted or convicted for such crimes. In addition to these primary aims, the researchers also investigated (4) registration violations (e.g., failure to register) were associated with sexual or general recidivism.

    Description

    These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers. Users should refer to the accompanying readme file for a brief description of the files available with this collection and consult the investigator(s) if further information is needed. Serial sexual assault is a pervasive problem: court record recidivism rates show that 10-15% of convicted sex offenders re-assault within five years and self-report studies suggest that 63-78% of males who have committed sexual assaults have raped more than one individual. The current study documents the scope of repeat sexual offending through a previously-unexplored method of documenting serial perpetration: DNA evidence in sexual assault kits (SAKs). Ultimately, the testing of N = 7,287 previously untested SAKs revealed n = 1,270 unique and identifiable perpetrators. When combined with information from lifetime criminal history records, 39.7% (n = 504) of this subsample of unique and identifiable perpetrators were found to be serial sexual offenders who committed, on average, 3.27 sexual assaults. This collection contains 10 SPSS files: ESCALATIONdata_2018-05-15.sav (1142 cases, 6 variables) Forensic_Outcomes_2018-04-03.sav (7287 cases, 7 variables) PERPdata_2018-04-03.sav (1424 cases, 12 variables) SAKdata_2018-04-03.sav (1675 cases, 6 variables) SAK_PERP_2018-04-03.sav (1691 cases, 12 variables) SSA_ARR_Arrests_Imputed_2018-09-03.sav (9826 cases, 24 variables) SSA_CHG_PA_Charges_Imputed_2018-09-03.sav (6052 cases, 24 variables) SSA_IDN_Offenders_2018-09-03.sav (1142 cases, 17 variables) SSA_INC_Incidents_Imputed_2018-09-03.sav (9550 cases, 16 variables) SSA_JUD_Judicial_Charges_Imputed_2018-09-03.sav (12522 cases, 30 variables) This collection includes demographic variables on offenders, including sex, race, age, and arrest region.

    Description

    In response to widespread public concern about convicted sex offenders being returned from prison, federal and state laws have been passed authorizing or requiring the notification of local communities where sex offenders would be living. The dilemma associated with community notification is balancing the public's right to be informed with the need to successfully reintegrate offenders within the community. Wisconsin was one of the 50 state jurisdictions that enacted a sex offender community notification statute. This project was an in-depth study of that state's experience from the vantage point of several groups affected by the community notification process. This data collection contains three surveys that were conducted from January 1998 through mid-September 1998: (1) a survey of 704 neighborhood residents at 22 community notification meetings throughout the state (Part 1), (2) a statewide survey of 312 police and sheriff agencies (Part 2), and (3) a statewide survey of 128 probation and parole agents and their supervisors from units with sex offender caseloads (Part 3). Variables in Part 1 include how respondents found out about the date and place of the community notification meeting, respondents' opinions of the purpose of the meeting, how clearly the purpose of meeting was stated, how the meeting went, outcomes, rating of information presented, if materials were handed out, if the materials were helpful, and respondents' level of concern after the meeting. Enforcement agency data (Part 2) include variables such as type of agency, type of jurisdiction, population size, if the agency designated a special staff member to coordinate the sex offender registration and notification functions, if the agency had policies regarding registration of sex offenders and community notification about sex offenders, if the agency attended statewide training, who participated in the Core Notification Team, what kind of information was used to determine a sex offender's risk to the community, which agencies registered to receive notice, and if the agency planned to update or expand their notification list. Additional variables cover the number of requests for information from Neighborhood Watch Programs, what identifying information about the offender the agency released, types of communication the agency received from the public after a notification had been issued, topics discussed in the public communication to the agency, benefits of the community notification law, difficulties in carrying out the requirements of the law, and methods developed to handle the problems. Probation and parole survey (Part 3) variables focused on characteristics of the respondent's supervising area, the number of agents assigned to the respondents' unit, the number of agents designated as Sex Offender Intensive Supervision Program (SO-ISP) agents or SO-ISP back-up agents, the number of child or adult sex offenders under probation or parole, if the respondent participated in any meetings regarding the provisions of the notification law and its implementation, if the supervisor received specialized training, and areas covered in the training. Other variables include whether the notification level was decided by the Core Notification Team, difficulties the respondent had with Special Bulletin Notification (SBN) offenders assigned to his/her caseload, if the respondent's field unit utilized SO-ISP or "high risk" agent teams to manage sex offenders, which individuals worked with the respondent's team, the type of caseload the respondent supervised, the number of sex offenders on the respondent's caseload, if the respondent used a special risk assessment or classification instrument for sex offenders, other information used to determine the supervision level for a sex offender, if child sex offenders were managed differently than other sex offenders, how often a polygraph was used on sex offenders, who paid for the polygraph, who chose the treatment provider, the number of supervision contacts with high-risk, SBN, or medium-risk sex offenders per week, victim policies and procedures used, rules or policies regarding revocation, and prerevocation sanctions used.

Description: Pursuant to the Sex Offender and Child Murderer Community Notification Law, 730 ILCS 152/101,et seq., the Chicago Police Department maintains a list of sex offenders residing in the City of Chicago who are required to register under the Sex Offender Registration Act, 730 ILCS 150/2, et seq. To protect the privacy of the individuals, addresses are shown at the block level only and specific locations are not identified. The data are extracted from the CLEAR (Citizen Law Enforcement Analysis and Reporting) system developed by the Department. Although every effort is made to keep this list accurate and current, the city cannot guarantee the accuracy of this information. Offenders may have moved and failed to notify the Chicago Police Department as required by law. If any information presented in this web site is known to be outdated, please contact the Chicago Police Department at srwbmstr@chicagopolice.org, or mail to Sex Registration Unit, 3510 S Michigan Ave, Chicago, IL 60653. Disclaimer: This registry is based upon the legislature's decision to facilitate access to publicly available information about persons convicted of specific sexual offenses. The Chicago Police Department has not considered or assessed the specific risk of re-offense with regard to any individual prior to his or her inclusion within this registry, and has made no determination that any individual included within the registry is currently dangerous. Individuals included within this registry are included solely by virtue of their conviction record and Illinois law. The main purpose of providing this data on the internet is to make the information more available and accessible, not to warn about any specific individual.

Anyone who uses information contained in the Sex Offender Database to commit a criminal act against another person is subject to criminal prosecution. Data Owner: Chicago Police Department. Frequency: Data is updated daily. Related Applications: CLEARMAP (http://j.mp/lLluSa).
