BOISE, Idaho -

A highway construction company owner who once led one of Idaho's most-powerful building groups has been sentenced to seven years in prison and ordered to pay $3.1 million in restitution.

The Idaho Statesman reports that 67-year-old Elaine Martin received the sentence Thursday in U.S. District Court in Boise.

Chief U.S. District Judge B. Lynn Winmill agreed to release Martin from the Ada County Jail for six weeks to take care of medical issues before going to prison.

Martin of Meridian, a former Associated General Contractors president in Idaho, was convicted in September of 22 criminal counts, including filing false tax returns and conspiracy to defraud the U.S. of millions of dollars.

Martin owned highway guard rail installer MarCon Inc., doing work in Oregon, Idaho, Nevada and Utah.
