LEXINGTON, Ky. (AP) — A grand jury has indicted four men in the killing of a pregnant woman who was hit by a stray bullet during a robbery.

Media outlets report 22-year-old Maryiah Coleman was walking her dog at night outside her Lexington apartment last Sept. 7 when she was shot. She and her unborn son, Jakobe, later died at the hospital.

Lexington police say 21-year-old Skylar Stigall and 20-year-olds Demetrioun Boaz, Joseph Fain and Saquan Freeman were trying to rob a man nearby when the victim ran, shots were fired, and the innocent bystander was struck.

The men are scheduled to be arraigned April 27 on charges of murder, fetal homicide and first-degree robbery. It's unclear if any have attorneys.
