WINSTON-SALEM, N.C - A grand jury indictment has revealed more about a grisly killing in North Carolina, where a man is accused of stabbing his roommates, chopping up their bodies, wrapping them in carpet and dumping them in the woods.

The Winston-Salem Journal reports 46-year-old Tyrone Donte Gladden was indicted Monday on charges of first-degree murder and dismembering human remains in order to conceal an unnatural death.

He’s accused of killing 40-year-old Devetta Carnetta Campbell and 36-year-old Gary Michael Craig Jr. in June 2017. Their families asked police to check the apartment that July. It was empty, stripped of its carpeting, but investigators found blood evidence, and then spotted a human torso in the woods nearby.

Gladden was arrested that August. His girlfriend told police he’d been researching “decomposing bodies” online.
