The state of Connecticut has put a database of over one million criminal convictions (dating back to January 1, 2000) online. Unlike some other states’ criminal conviction databases, this one also includes minor infractions like traffic offenses. You can search it at http://www.jud2.ct.gov/crdockets/SearchByDefDisp.aspx . Using it is free.
You can search by last name, first initial, year of birth and range of years (birth dates are not searchable and not displayed on the site) court location, and category type (criminal or motor vehicle.) Results are delivered in a table that includes defendant year, birth name, court, docket number, disposition (guilty, bond forfeit, etc.) and the sentencing date.
Clicking on a name provides a page that includes arresting officer’s name (sometimes it’s a name sometimes it’s a police department indicator), infraction and type, offense date, plea, verdict finding, date, and fines. (Yup, even down to the $35 speeding ticket.) Sometimes there is no fine, but there is sentencing information.
Be sure to check out the disclaimer for additional information on what is and isn’t included in this database, and how often it’s updated.
