IDAHO FALLS, Idaho (AP) — An eastern Idaho judge says he won't reduce a life sentence for a man convicted in the murder of Kristy Aschliman.

The Post Register reports that 7th District Judge Jon Shindurling turned down the request from Adan Arroyo on Wednesday. Arroyo currently isn't eligible for parole until he serves at least 25 years in prison.

He asked the judge to reduce that minimum term to 15 years. Arroyo originally faced the death penalty for the January 2013 murder. Prosecutors said Arroyo chased down his victim after she jumped from a moving car, and shot her four times in the head.

Her body was left on the side of a road in the rural town of Ammon. Arroyo is now appealing his sentence to the Idaho Supreme Court.
