Fort Campbell soldier Brent Burke will spend the rest of his life behind bars.
He was found guilty in military court on charges connected to the deaths of his estranged wife and her former mother-in-law.
Burke had been tried four times in civilian court, but each case ended in either a mistrial or hung jury. Tracy Burke and Karen Comer were found dead at a Hardin County home in 2007. The jury returned the verdict after just three hours of deliberations. He was sentenced to life without parole on the two premeditated murder counts.
