PORTLAND, Ore. (KOIN 6) — The spurned lover of a young woman will spend years in prison for his role in a 2013 slaying in Southeast Portland.

Corey Hill was sentenced to 12 years in prison after pleading guilty to 1st-degree manslaughter in the death of Precious Jackson on Nov. 1, 2013. The shooter, Antonio Sanders, was sentenced to 18 years.

Hill was romantically involved with a woman, who then left him for Precious Jackson. That upset Hill, who then sought help from friends to kill Jackson.

Hill, Antonio L. Sanders Jr. and 2 others showed up at the apartment complex where Jackson and the other woman were staying.

Sanders pulled out a .380 semi-automatic pistol and started shooting at Jackson at close range, court documents state. He plead guilty to one count of first-degree manslaughter with a firearm.

Both were formally sentenced on Tuesday by Judge Eric J. Bergstrom.
