A man and woman in Montana have been charged with homicide after their roommate filed a police report last week alleging that two people had been murdered in their Missoula home.

When police reported to the residence to investigate on Friday, they found human remains in plastic tubs filled with chemicals, according to The Missoulian. Tiffanie Pierce, 23, and Augustus Standingrock, 26, have been charged with deliberate homicide and are each being held on $2 million bail.

The roommate reportedly told police he woke up to the sound of a woman screaming and found Pierce and Standingrock washing off blood in the shower. When confronted, Pierce allegedly told the roommate that she and Standingrock had attacked two people who had visited the home and said the bodies were in the basement.

Indeed, a man and a woman’s body were found in the basement, though the victims have not yet been identified. According to KRVT, when police arrived to the home, Pierce and Standingrock were still there. Standingrock was reportedly holding a gun and a bloody cloth, but police were able to subdue him.

Police additionally found a knife and an axe covered in blood in the home, along with human tissue, according to the newspaper.

Pierce has reportedly been under investigation for a previous stabbing incident last month.

According to CBS News, the suspects have not yet entered pleas.
