JACKSON (AP) — A 38-year-old-man and a woman already facing state charges over three deaths during a Mississippi robbery now face federal charges.

Joshua Garcia, of Vancleave, pleaded not guilty in federal court Tuesday to robbery, discharging a firearm causing the murder of three individuals, and being a felon in possession of a gun. Thirty-six-year-old Jamison Townsend, of Blue Springs, Missouri, is scheduled to appear Friday on charges of robbery and discharging a firearm causing the murder of three individuals.

Both could face the death penalty if convicted.
