GRAND RAPIDS, Mich. (AP) — A western Michigan man imprisoned for killing his half brother has been charged with murder in a second slaying.

Grand Rapids police say 22-year-old Royale Runyon was charged Thursday with open murder, felony murder and a weapons charge in the December 2012 shooting death of 20-year-old Eve'vanna Galloway.

Runyon is serving a sentence of at least 30 years in prison for second-degree murder in the slaying of his half brother, Mahdi Hayes, five days after Galloway was killed.

WZZM-TV reports Galloway was Hayes' former girlfriend.
