MISSOULA – Tiffanie Pierce will now face one more felony count for her alleged involvement in a robbery on Montana Street that left one victim with stab wounds.
According to court documents, Pierce broke into a home with her boyfriend Augustus Standingrock and then stabbed the victim while demanding drugs and money from her.
The Missoula County Attorney’s Office changed one felony count from assault with a weapon to a felony robbery charge and also added a count of aggravated burglary on Friday.
The prosecution says that the amended charges better fit the crimes of the defendant and Pierce will now be facing a total of five felonies.
She will face two charges of deliberate homicide from her involvement in the killing of two people in her Strand Avenue home. That was also done with Standingrock who plead guilty to his involvement back in December.
Pierce will next be seen in court March 15.
