(CNN) - The Utah Department of Workforce Services said Friday it has identified at least two employees believed to be involved in creating a list containing the personal information of a purported 1,300 alleged illegal immigrants.

"At this point we don't think it was a very large conspiracy. We think it was two, maybe. We have suspicion of a couple of more people, a very small group," said Kristen Cox, the executive director of the Department of Workforce Services.

"Release of such private, sensitive information is deplorable," Gov. Gary Herbert said in a news release. "We immediately took action to discover the origins of this list, and I'm pleased with the hard work of the Department of Workforce Services. When someone does business with the state of Utah, they deserve to know that their private information will be kept private."

Herbert told CNN's John King on Friday night that the 1,300 people have Hispanic names and not all of them are in the state illegally.
