Assistant Prosecutor Larry Frye told the judge his office offered Pauley mercy based on his confession and cooperation with police after the incident.
Rosiek's brother, Brad Booth, 46, of Ohio, spoke before Pauley was sentenced.
"I never thought in my mind once about mercy for you, but mercy for my niece," Booth said, referring to Rosiek's daughter, Misty Hall. "Just so she doesn't have to go through a trial."
Pauley's 21-year-old daughter, Brittany, sat on the edge of her seat, leaning in close behind her father during the hearing, and said, "I love you, Dad," before his plea.
Outside the judicial building before the hearing, Hall, 33, of Oak Hill confronted Brittany Pauley, and court officials separated the two families before and after the hearing.
"It must be nice to have her parent," Hall said through tears. "It's not fair she'll still be able to write him letters and visit him."
