YORK, Neb. (AP) — A southeastern Nebraska judge is again contemplating whether to delay the resentencing of a man convicted of killing his 12-year-old sister when he was 14.

York County District Judge James Stecker is weighing whether to move ahead with the resentencing of 42-year-old Sydney Thieszen, or wait until the U.S. Supreme Court clarifies guidelines on the sentencing of juvenile killers.

In 1987, Thieszen bludgeoned and shot his adopted 12-year-old sister in their Henderson-area home. Prosecutors said he was afraid she would tell police he was running away.

In December, the judge sided with prosecutors to delay the sentencing until the Supreme Court ruled in a Louisiana case, which had been expected this spring. But that case settled in February.
