MISSOULA – The jury trial for a woman charged in the murder of two people has been pushed to a later date.

Tiffanie Pierce is facing four felony counts stemming from two different incidents.

In July of 2017 Pierce is accused of breaking into someone’s home off of Montana Street and stabbing a woman multiple times.

The victim told police that Pierce demanded money and drugs from her.

Pierce’s boyfriend, Augustus Standingrock, was allegedly with her for that break in but did not take part in the assault according to court documents.

Later in August 2017, Pierce is accused of killing 15-year-old Marilyn Pickett and 24-year-old Jackson Wiles in the basement of her home on Strand Avenue and then attempting to dispose of the bodies in tubs filled with chemicals.

A police investigation showed that 15-year-old Marilyn Pickett and 24-year-old Jackson Wiles were stabbed to death in a Strand Avenue home before their bodies had been placed into plastic tubs filled with chemicals.

Standingrock was present for those homicides and pleaded guilty for his involvement back in December.

During the trial Standingrock said he handed a knife he had used to stab one of the victims to Pierce and said that he knew what would happened if he did so.

The jury trial for the Montana Street break-in will be on March 1.

The double murder trial is now set for April 12 in Missoula County District Court.

Pierce will also appear in court on Friday for a status conference.
