After eight hours of deliberation, an Aitkin County jury Friday found Ardell Manthey guilty of murdering her husband.
Ardell Manthey, 70, was immediately sentenced to life in prison by Aitkin County Judge John Smith.
After more than a year of investigation, a grand jury April 1 indicted Ardell Manthey on a charge of premeditated first-degree murder for the March 5, 2003, shooting death of Francis Darrell Manthey, 69, at their Hill City home.
Aitkin County Sheriff Dennis Landborg said based on the investigation by his office and the Minnesota attorney general's office -- and outlined by the prosecution in the trial -- Ardell Manthey had accrued gambling debts and shot her husband when he confronted her about it.
"She had been doing things to try to keep the amount of money she spent from him," Landborg said.
Francis Manthey was found lying in a bedroom with two gunshot wounds, Landborg said.
