SALT LAKE CITY -- Utah officials said Friday they have identified at least two state workers who apparently accessed confidential documents to create a list of 1,300 purported illegal immigrants that was mailed to law enforcement officials and the news media.
Gov. Gary Herbert said the employees work for the Department of Workforce Services, which administers food stamp programs and other public benefits.
The employees have been placed on administrative leave.
"It's a very small group. The people we've identified certainly have some strong political opinions and seem to be frustrated with some of the issues around immigration," said Kristen Cox, executive director for the department.
"I think it's an immense hypocrisy to talk about taking people to task for being illegal and doing so by breaking the law."
Newspapers started receiving the list of names and personal information this week, and its publicity created widespread fear in the Hispanic community.
The anonymous mailing said it also was sent to immigration officials. It demanded that those on the list be deported, although some named have said they are in the country legally.
"This tactic by these rogue employees to go out and to single out individuals and their families -- in some cases falsely accusing people of an illegal status -- is in fact deplorable," Herbert said.
Cox said a few more people may be implicated in the leak of the names, but she's confident that the core group responsible for the list has been identified.
Hispanic advocates applauded how quickly the state acted to find the source of the leak and to assure the community that state policy doesn't allow for just anyone to access private information.
"The governor took the first step today to bring that trust back again," said Tony Yapias, former director of the Office of Hispanic Affairs.
Intentionally releasing a private record in Utah is a misdemeanor punishable by up to six months in jail and a $1,000 fine. If someone stole such a record, it could be prosecuted as a felony with a penalty punishable by up to five years in prison and a $5,000 fine.
"We will begin an immediate, aggressive, formal investigation," Utah Attorney General Mark Shurtleff promised Friday during a conference call with national and local Hispanic leaders.
Herbert said accessing the private information and distributing it to federal immigration authorities is also a violation of federal law.
Shurtleff said he would seek the help of the U.S. Attorney's Office. "We're talking serious, felony-level crimes."
The list contains Social Security numbers, birth dates, workplaces, addresses and phone numbers. Names of children are included, along with due dates of pregnant women.
Cox said most people on the list are there because their children are receiving benefits.
Herbert said two benefits administered by the state -- food stamps and prenatal care -- would provide information that could indicate someone is in the country illegally. The state keeps records of the relatives of those receiving benefits because it has to know what each person's household income is before benefits are issued.
Officials continued investigating the list Friday even though state employees usually have the day off as part of the state's four-day workweek to cut energy costs.
The investigation comes as Herbert, a Republican, prepares to host a public immigration summit Tuesday.
Herbert has said he will sign an immigration bill into law next year if he's in office, but it's unclear how closely it might mirror one lawmakers recently passed in Arizona.
Arizona's law, which takes effect July 29, directs police enforcing other laws to determine a suspect's immigration status if there is reason to believe the person is in the U.S. illegally.
The Obama administration has sued Arizona to throw out the law and keep other states from copying it.
