SHEBOYGAN, WI (WTAQ) - A Sheboygan teenager has been found competent to stand trial in the September death of his great-grandmother.

Next is a hearing in January to determine if the case will be moved to juvenile court.

The judge made his ruling Friday, basing it on a court-ordered mental health evaluation. 13 year old Antonio Barbeau and his friend of the same age Nathan Paape are charged with first-degree intentional homicide.

They are accused of beating 78 year old Barbara Olson to death in her home in Sheboygan Falls last September. They allegedly used a hammer and a hatchet. Investigators say they then stole money to buy marijuana and pizza.
