The state's registry page says in three sentences what the Department of Emergency Services and Public Protection provides: an updated searchable record of sex offenders giving each offender's last known address and physical descriptors as well as the location, date and details of the offense, compiled without any consideration or assessment of the specific risk that any individual will offend again and without any determination that anyone listed is currently dangerous. The law behind it is chapter 969 of the General Statutes, sections 54-250 through 54-261, which the department's State Police Sex Offender Registry Unit administers; section 54-257 required the department to establish the registry by January 1, 1999, to develop the forms with the Chief Court Administrator, the Department of Correction and the Psychiatric Security Review Board, to enter every registration and notify the local police department or state police troop where the registrant lives or plans to live, to notify the police with jurisdiction over any college where a registrant studies or works, to notify the other state when a registrant reports a residence there, and to send every registration, conviction record, photograph and fingerprint card to the FBI for the national registry. The unit's report on 2010 describes the public website: searchable by last name, town or ZIP code or by viewing the entire list of registrants, free of charge and with no need to identify oneself, with mapping of each registrant and an email alert whenever a registrant moves into a chosen radius of an address, features added when the new public site launched in October 2009.
Three things set the Connecticut system apart: registration is with the commissioner of the department, on the forms and at the locations the commissioner directs, rather than with a town police chief; the term is fixed by the class of offense, ten years or life, with no risk tiers; and the address of every registrant is verified by mail every 90 days, the missed form sending the local police for an arrest warrant. The police department or resident state trooper for any Connecticut town is on the Connecticut county pages.
- Search: the department's searchable record, by last name, town or ZIP code or the full list, with a map for each registrant and email alerts by radius, reached from the state registry page; every police department and state police troop also keeps the records open during business hours.
- Duration: ten years from release into the community for a criminal offense against a minor, a nonviolent sexual offense or a felony committed for a sexual purpose, life for a sexually violent offense, for a second such conviction or for first degree sexual assault of a victim under 13, and the other jurisdiction's term for an offender convicted elsewhere.
- Verification: a nonforwardable form mailed every 90 days and returned by mail, fax or email within ten days, an in person check where there is no mail delivery, and a new photograph at least every five years.
- Penalty: a class D felony for failing to register or to report a change of name, address, internet identifier, school or job without undue delay, once the failure has lasted five business days.

Who registers: the three classes of offense
Section 54-250 sorts the registrable crimes into classes. A criminal offense against a victim who is a minor covers the listed subsections of risk of injury to a minor, first degree sexual assault of a child under 13, the age based subdivisions of second degree sexual assault, third degree sexual assault with a minor, promoting prostitution and patronizing a prostitute involving a minor, enticing a minor, and the child pornography and obscenity offenses in sections 53a-196a through 53a-196f, plus kidnapping, unlawful restraint, custodial interference and stalking when the court finds the victim was under 18, and any attempt, conspiracy or accessory liability for them.
A nonviolent sexual offense means fourth degree sexual assault or the listed subdivisions of voyeurism, with the same attempt and conspiracy coverage. A sexually violent offense means first degree sexual assault, aggravated first degree sexual assault, second degree sexual assault, third degree sexual assault and third degree sexual assault with a firearm outside the subdivisions assigned to the minor class, the former spousal or cohabitant sexual assault offense repealed in 2019, and first degree or aggravated kidnapping when the court finds an intent to sexually violate or abuse the victim.
A conviction means a judgment on a guilty plea, a nolo contendere plea or a verdict, whatever appeal is pending, and a finding of not guilty by reason of mental disease or defect triggers the same duties. Section 54-251 reaches anyone convicted or so found of a minor victim or nonviolent offense and released into the community on or after October 1, 1998; section 54-252 anyone convicted of a sexually violent offense and released on or after October 1, 1988; section 54-253 anyone convicted in another state, a federal or military court or a foreign jurisdiction of a crime substantially the same as the listed ones or one that requires registration there, who lives, works or studies in Connecticut; and section 54-254 lets the sentencing court order ten years of registration for any felony committed on or after October 1, 1998 that it finds was committed for a sexual purpose, meaning that a purpose of the crime, even one arising midway through it, was sexual contact or intercourse without consent.
Registering: three days, and the changes without undue delay
A person subject to section 54-251 or 54-252 registers within three days of release into the community, or before release at the time the Commissioner of Correction directs when in that commissioner's custody, giving the name, the identifying factors, meaning fingerprints, a photographic image, any other identifying characteristics the commissioner requires and a blood or other biological sample for DNA analysis unless one was already taken, the criminal history record, the residence address and any email address, instant message address or similar internet identifier, and a sexually violent offender adds documentation of any treatment received for a mental abnormality or personality disorder; an offender convicted elsewhere registers without undue delay on taking up residence, and a nonresident registered elsewhere who works, carries on a vocation or studies here registers too.
Release into the community means any release by a court after conviction, a sentence of probation or any sentence that does not put the offender straight into the Commissioner of Correction's custody, release from prison on parole, to a halfway program, at the end of the maximum term or to probation supervision, and release or temporary leave from the Psychiatric Security Review Board. Before accepting a guilty or nolo contendere plea to a registrable offense the court must tell the defendant that a conviction brings registration and find that the defendant understands it, and section 54-256 has every court, the Commissioner of Correction and the review board make completion of the registration package a condition of any conditional release, hand the person a written summary of the duties, and, for a person released unconditionally who declines to complete the package, send the commissioner the name, release date, expected address, criminal history, treatment history and known internet identifiers and tell the person of the three day duty.
Once registered, a person reports a change of name, a change of residence address, a new or changed internet identifier, employment, a vocation or enrollment at any trade or professional institution or college in Connecticut and any change in it, and employment, a vocation or enrollment in another state, each in writing to the commissioner without undue delay, registering as well with the other state when the new residence, job or school lies there and that state has a registry; employment for these purposes means more than 14 days of full or part time work, or more than 30 days in a calendar year, paid, volunteered or for educational benefit, and a student is anyone enrolled full or part time at any public or private educational institution from a secondary school to a university.
Ten years or life, and the court exemptions
A section 54-251 registrant maintains the registration for ten years from the date of release into the community, except that one with any prior conviction for such an offense, or one convicted of first degree sexual assault of a victim under 13, registers for life; a section 54-252 registrant registers for life; a section 54-253 registrant stays on the registry until released from the duty in the state, federal or military system or foreign jurisdiction of conviction; and a section 54-254 registrant registers for the ten years the court ordered.
The ten year clock runs from the release date, and section 54-257 lets the department suspend a registration while the registrant is incarcerated, under civil commitment or living outside Connecticut, withdrawing the record from public access and pausing the verification mail, without moving the expiration date. Two exemptions rest with the court: for second degree sexual assault under subdivision one of section 53a-71(a), the age based offense, the court may exempt a person who was under 19 at the time of the offense when registration is not required for public safety, a discretion the courts have read as available even years after the registry entry; and for fourth degree sexual assault under subdivision two of section 53a-73a(a) and the listed voyeurism offenses the court may exempt a person when registration is not required for public safety.
An applicant for either exemption notifies the Office of Victim Services and the Victim Services Unit of the Department of Correction, which tell any victim who asked to be told, and the court considers the victim's statement before deciding. Section 54-255 lets the court restrict the registration information of a person convicted of the former spousal or cohabitant sexual assault offense to law enforcement use only when public safety does not require dissemination and publication would likely reveal the victim's identity in the victim's own community, lifting the restriction if either finding changes.
The 90 day verification mail and the five year photograph
Under section 54-257(c) the department verifies every registrant's residence address by mailing a nonforwardable verification form to the last reported residence address, which the registrant signs to confirm living there and returns by mail, fax or email by a date ten days after the mailing, the form warning that failing to return it or giving false information violates the registration statute; a registrant at an address with no residential mail delivery is verified in person by the local police department or the state police troop, every registrant is verified this way every 90 days after the initial registration date, and when a form is not returned the department notifies the local police or troop for the last reported address, which applies for a warrant for the registrant's arrest.
Addresses outside the state are not verified. Section 54-257(d) has the department keep in the registry the most recent photograph taken by the department, the Department of Correction, a law enforcement agency or the Court Support Services Division and retake every registrant's photograph at least once every five years, and every registrant must also sit for a new photograph on the commissioner's request; section 54-257(e) and (f) have the department revise the record whenever a superior or probate court reports a court ordered name change and notify other agencies, the Judicial Department and the local police of any new name.
The unit's 2010 report gives the scale of the mail: registrants have ten days to return the form or face arrest for a class D felony, 652 registrants were non compliant at the time, the unit updated the photographs of 1,056 registrants that year, and its 1,263 investigations of registrants in violation were forwarded to the local agencies where the registrants last lived so that they could obtain the arrest warrants.
What the public sees, and who is told
Section 54-258 makes the registry a public record, accessible during normal business hours and through the internet, with the department issuing notices to all print and electronic media in the state at least once a calendar quarter about how to reach it, and every local police department and state police troop keeping a record of the registration information sent to it and opening that record to the public during business hours.
Any state agency, the Judicial Department, a state police troop or a local police department may at its discretion notify any government agency, private organization or individual of registration information when it believes the notice necessary to protect the public or any person, and whenever a registrant is released into the community or reports a new residence address the department emails the superintendent of schools for the district where the registrant lives or plans to live and the chief executive officer of the municipality, giving each the same registry information the public sees online, a notification the unit counted 3,224 times in 2010.
Three things stay closed: the identity of any victim and any treatment information given to the registry, released only to government agencies for law enforcement or security purposes; registration information a court restricted under section 54-255; and a registrant's email, instant message or other internet identifiers, which the department may release only for law enforcement or security purposes under its regulations, to electronic communication and remote computing providers and website operators among others.
When a registrant completes the term or is otherwise released from the duty, the department tells the troop or local police for the last address and all three remove the name and information from the registry, and section 54-258a requires every agency giving public access to post the warning that anyone who uses the information to injure, harass or commit a crime against a registrant or anyone else is subject to prosecution.
The registry in numbers
The unit's public reports put figures on the system. In 2010 it completed registrations on 339 new registered sex offenders, bringing the total living, working or attending school in Connecticut to 5,231 at the end of the year; 188 registrants completed their ten year terms and were removed after investigations verified that they met every requirement for removal; the website drew 509,898 hits; and since the October 2009 relaunch 6,881 households had signed up for email alerts and 37,179 alerts had been sent, the release listing the number of registrants in each local jurisdiction.
The report on 2006 counted 4,461 registered sex offenders, of whom 400 had been convicted in federal, military or other state courts and moved to, worked in or studied in Connecticut, 345 investigative reports on registrants who failed to verify their addresses, 458 registrants who had failed to verify, the not in compliance cases, people who had never registered since the registry began in 1998, cut from 26 in 2005 to 19 in 2006, and more than nine million hits on the website that year.
Reading a Connecticut result
An entry on the department's record gives the last known address, the description and the offense with its location and date, and the class of offense tells the term, ten years from release or life; nothing in it rates the person's risk, because the department assesses none. A name absent from the site may be a registrant whose registration is suspended while in prison, in a hospital or living out of state, one whose ten years have run and been verified, one a court exempted or restricted, or one not yet entered from a fresh release.
The local police department or state police troop holds the same record, the superintendent of schools and the town's chief executive have the email, and the unit holds the verification mail and the photograph file.
