MORRIS -- The youngest of three brothers involved in the murder of their mother was sentenced Monday to 15 years in prison.

Jacob Seth Cobb, 18, had pleaded guilty to murder in the second degree while committing assault in the third degree in the death of 50-year-old Tamara Lee Mason.

Dylan Cody Clemens, 26, was sentenced to nearly eight years after pleading guilty to being an accessory after the fact to Mason's murder.

Andrew Quinton Cobb, 19, was ordered to serve 22½ months. He also pleaded guilty to being an accessory after the fact.

The brothers appeared Monday before Judge Gerald Seibel in Stevens County District Court. Andrew Cobb was released afterward with credit for time already served.

Mason was reported missing Dec. 27, 2010, by Clemens. Her body was found in July 2011, buried in the backyard of the Alberta home where she lived.

Seibel told Jacob Cobb on Monday that he was concerned this would not be the last time Jacob was in court.

"You're going to spend a long time in prison, but a longer time out," said Seibel. "You need to find another way to learn to deal with people."

Under the terms of Andrew Cobb's plea agreement, Judge Seibel was asked to consider a less severe sentence.

Attorney Kent Marshall, argued that Andrew has no criminal history and that spending more time in jail would not benefit him or the state.

Andrew said Mason "meant the world" to him. "I'm very sorry for my actions; not a day goes by that I don't think about what I did."

Seibel said that although it would never be entirely clear what happened the night Mason was murdered, it appeared that Andrew played a "more passive than active" role in Mason's death.

"You are one of three brothers who have the chance to be the man your mother would have you to be," Seibel said. "That's an obligation you have to fulfill."

The criminal complaint said Jacob Cobb strangled his mother on the living room floor. Then his brother Andrew allegedly put a plastic bag over her head and tightened a belt around her neck. Clemens allegedly drove her body to South Dakota and Glenwood before storing the corpse in a shed for months until the ground thawed.
