ST. PAUL (AP) - The Minnesota Supreme Court has ordered a new trial for a man convicted of aiding in a murder committed by his father on a Kandiyohi County farm.

The justices ruled Wednesday the jury in Timothy Huber's trial got erroneous instructions for determining if he was guilty of intentionally aiding his father in committing second-degree murder.

The high court said the bad instructions let the jury convict Huber in 2013 for his mere presence near the killing of Albertville teacher Timothy Larson on the victim's family farm near Belgrade in 2011, which came after years of animosity between the men. He was sentenced to 25 1/2 years in prison.

The defendant's father, Delbert Huber, admitted shooting Larson. He pleaded guilty to second-degree murder. He died in prison in 2014 at age 83.
