GOLDEN, Colo. (AP) — A man has been sentenced to four years in a Colorado prison for leaving his friend as she died of a methamphetamine overdose.

Jefferson and Gilpin Counties District Attorney Pete Weir says Nathan Hale pleaded guilty in May to charges of reckless manslaughter and distribution of a controlled substance in relation to the death of 25-year-old Natasha Rowley.

Prosecutors say Hale, who is 37 and lived in Nebraska, brought 14 grams of methamphetamine when he came to Arvada to help Rowley move in June 2017. They say both used the drug but Rowley soon went into “medical distress” and by morning had begun “moaning and gasping for air.”

They said Hale left the house without helping Rowley or calling for help. He was arrested in December.
