RAPID CITY, S.D. (AP) — A 32-year-old Rapid City man who killed his ex-girlfriend and her unborn child will spend the rest of his life behind bars.

Circuit Judge Jeff Davis on Monday handed down the mandatory life prison sentence to Michael Young. Young last month pleaded guilty to second-degree murder in the April 2012 stabbing death of 30-year-old Morgan Myers in a Wal-Mart parking lot.

Myers was pregnant with Young's child. She had split up with Young and filed a restraining order against him.

Prosecutors earlier chose not to seek the death penalty against Young. But he will not be eligible for parole.
