Western Montana residents Tiffanie Pierce and Augustus Standingrock were charged in the stabbing deaths of two people whose corpses were later found in plastic tubs of chemicals in the pair's home, according to CBS.
The names of the victims have not yet been released.
Pierce had allegedly purchased the chemicals that would be used to help dispose of their victims' remains.
Pierce's roommate had discovered her and Standingrock washing blood off their bodies after being awoken by the sounds of a woman screaming. Pierce told him there was a body in the basement. The roommate left, but the next day Pierce told the roommate at work that they had "killed a couple people last night."
Pierce told the roommate that they had invited the two victims over and took them to the basement before Standingrock attacked one. Pierce attacked the other to prevent them from escaping. Both victims were found to have died of stab wounds.
Pierce is also the subject of an investigation related to a home invasion and stabbing from earlier this summer. "Where's the money, where's the drugs?" asked the intruder of the victim in that case.
Bail has been set at $2 million for both Pierce and Standingrock.
"There's no combination of (release conditions) that would ensure that members of our community would be safe," Missoula County Attorney Kirsten Pabst told Justice of the Peace Marie Andersen on Monday, according to Time.
They have not entered a plea yet.
