Motion to suppress evidence has been denied in Missoula double-murder case

MISSOULA – A motion to suppress evidence in the trial of Augustus Standingrock, accused of killing two people in 2017, has been denied by Judge James Wheelis. But the defense will get their other wish of a delayed court date.

Standingrock is charged for the August 2017 murders of 15-year-old Marilyn Pickett and 24-year-old Jackson Wiles. Standingrock’s girlfriend, Tiffanie Pierce, is accused of committing the murders with him, and both are accused of attempting to dispose of the bodies in chemical-filled barrels in their basement.

On October 1, Standingrock’s defense team argued that the state has gathered a substantial amount of evidence in the case and submitted the evidence to the State Crime Lab, but has yet to receive any results.

The defense argued that all DNA evidence should be suppressed unless the case is continued in order to allow the defense time to review results they receive and develop a case strategy for the processed evidence.

Wheelis denied the motion, ruling that the state and the crime labs have done their best to process the evidence in a timely manner. Wheelis did, however, agree with the defense that a new trial date will give the defense enough time to review the processed evidence and come up with their defense strategy.

The new trial date has been reset for January 4, with a status hearing set for December 21.

(AUGUST 21, 2017) Court documents have provided details about the murder of two people found dead at a home in Missoula last week.

On Thursday, 23-year-old Tiffanie Pierce and 26-year-old Augustus Standing Rock were taken into custody.

The victim’s identities have not yet been released.

Prosecutors say in court documents that on August 17th, a confidential informant reported that a friend of his who was roommates with Pierce came to his home in the middle of the night because she told him that she and Standing-Rock had “stabbed someone.”

The roommate said he was at first awakened by a woman screaming. He went into the kitchen and saw blood, and reported that the couple had been in the bathroom washing blood off themselves before Pierce told him what happened. Pierce told him that there was a dead woman’s body in the basement.

After learning this the roommate left the house.

Pierce came to the roommate’s work later telling him that her and Standing Rock brought a couple of people over, took them into the basement, and attacked one. When the other tried to get away they stabbed that person also, killing them both.

After the report, police obtained a search warrant for a home in the 1900 block of Strand Avenue.

Officers found Pierce and Standing Rock at the home. Standing Rock had a bloody cloth around his hand and was at first holding a gun, before complying with police. The two were taken into custody without incident.

Police found the handgun in the home, along with two bodies in the basement – one male and one female.

The bodies had been placed into plastic tubs filled with chemicals. Investigators also found knives and an ax covered in blood, and what appeared to be human tissue.

The initial investigation indicates that the two victims died from stab wounds.

They also determined that Pierce had recently purchased cleaning agents, plastic tubs, and chemicals used in the tubs where the bodies were found.

Both defendants are expected to make their initial appearance in Missoula County Justice Court on Monday afternoon.
