SHEBOYGAN, Wis. (AP) -- A judge has ruled a 13-year-old Sheboygan boy is competent to stand trial in the killing of his great-grandmother in September.

Judge Timothy Van Akkeren found the boy competent Friday, based on a court-ordered mental health evaluation.

The Sheboygan Press reports the boy's attorney, who requested the evaluation, did not challenge the ruling.

The boy and a 13-year-old friend are charged with first-degree intentional homicide for allegedly bludgeoning to death 78-year-old Barbara Olson at her Sheboygan Falls home on Sept. 17 with a hammer and hatchet. The boys are accused of ransacking Olson's house and stealing money to buy marijuana and pizza.

Attorneys for the other boy did not seek a competency evaluation.

The case now moves to a January hearing on whether to move the case to juvenile court.

SHEBOYGAN, Wis. (AP) -- A judge will decide whether two 13-year-old Sheboygan boys will stand trial for allegedly killing and robbing the one boy's great grandmother.

A preliminary hearing is scheduled for Tuesday afternoon.

Earlier Tuesday, a judge denied a motion from defense attorneys to delay the hearing. Attorneys argued they didn't receive access to all the state's evidence but the judge ruled state law doesn't require it before the hearing.

Prosecutors allege the boys used a hatchet and hammer to kill 78-year-old Barbara Olson's home on Sept. 17 before stealing jewelry and a car. Her daughter discovered her body in the garage two days later. The boys are charged as adults.

One boy's attorney, George Limbeck, tells The Sheboygan Press (http://shebpr.es/QL7OlJ) he will push to have the case sent to juvenile court.
