According to a search warrant application, in the early hours of July 23, officers were dispatched to a call for an apparent attempted deliberate homicide in a Missoula home.
A male and a female, later identified by police as Standing-Rock and Pierce, entered the residence during the night. Pierce allegedly stabbed a woman sleeping there multiple times in the face, neck, abdomen and thigh with a knife.
The victim survived, but later told police that “it seemed like they were surprised to see me” and that Pierce allegedly asked several times “where’s the money, where’s the drugs?” before stealing phones and a small amount of cash.
Video surveillance from a nearby auto shop, cellular data, witness corroboration and computer analysis by detectives allowed the Missoula police to identify Pierce as a suspect. The police then executed a search warrant at Strand Avenue on Thursday, Aug. 17, when they found evidence of “other” crimes, including homicide.
Standingrock was on conditional release at the time of the search, for the suspended portion of felony sentences for assault with a weapon and criminal endangerment.
