Utah-based Deseret Health Group will shut down its Saratoga nursing home, according to the Wyoming Department of Health.

The department received an official notice late Wednesday night, said health department spokeswoman Kim Deti.

Under federal rules, nursing home operators must give 60 days notice of a closure. If an operator does not meet its obligations, the state attorney general can pursue civil and criminal action. The Department of Health could also help relocate residents if needed.

The Saratoga facility is home to about 30 people, and employs about 30 workers.

An administrator in Saratoga said she had been told the company folded.

Health Management Services, a Montana-based company, is considering purchasing or leasing the facility. Deseret has given the company until Friday to offer a proposal, said Health Management CEO and President Joe Rude.

Deseret officials declined to comment. The company announced Monday it is closing its Rock Springs facility, where about 90 employees care for about 60 people.

Deseret operates senior health care facilities in Kansas, Minnesota, Nebraska and Utah, in addition to its Rock Springs and Saratoga sites, according to its website.

One Deseret executive was sentenced to 366 days in prison after he pleaded guilty to filing a false tax return in 2003, according to the United States Attorney's Office -- District of Utah. Jon Robertson, founder of Deseret, owed the IRS $150,000 in restitution as part of his sentence.
