Deann Kimble, 53, was sentenced Thursday in Cheyenne County District Court to time served and three years of probation.
Kimble pleaded no contest in April to a felony charge of aiding a suicide after prosecutors dropped a charge of concealing human remains.
Deputies have said Kimble told them that she promised 61-year-old Russell Kimble that she would not intervene when he decided it was "his time to die."
She told investigators that Russell Kimble shot himself on March 22 with a youth model 20-gauge shotgun inside their rural Sidney home, believing he was gravely ill. She says she went outside and sat in their van as he made his final preparations.
Investigators say Deann Kimble then wrapped his body is a shower curtain and sheet and buried it in a shallow grave.
