Idaho Judge Declares Mistrial on Day One of Twin Falls Taxidermist’s Poaching Evidence Trial
Mistrial Halts Proceedings Against Taxidermist Facing Poaching-Related Charges
A Twin Falls judge declared a mistrial on the first day of proceedings against a local taxidermist accused of withholding and altering evidence in connection with a high-profile Idaho poaching investigation, halting the case before it could reach the jury.
Twin Falls District Judge Benjamin Cluff brought the trial of taxidermist Tom Schiermeier to an abrupt end during cross-examination of the first witness — after a jury had already been seated and opening statements delivered. The mistrial was triggered by unresolved legal questions about what records Idaho law actually requires taxidermists to keep.
“I do think that the testimony that’s been introduced, how it’s been answered, how it’s been started, is going to interfere with a fair trial, so I’m granting a mistrial,” Judge Cluff said from the bench, according to reporting by KIVI.
Schiermeier had originally faced two felony counts and six misdemeanors when he was first charged in June 2024. By the time the case was set for trial this week, prosecutors had reduced the charges to one felony and two misdemeanors. The state accused Schiermeier of improperly maintaining records and preparing false evidence.
Charges Rooted in Major Idaho Poaching Investigation
The case against Schiermeier grew out of a broader Idaho Department of Fish and Game investigation into two significant poaching cases that ultimately resulted in criminal convictions. As part of that investigation, Fish and Game officers requested records of all taxidermy orders processed at Schiermeier Taxidermy during a window between August and November 2023.
Investigators say they were initially provided with a list of 26 customer orders. When officers returned with a search warrant, they reported discovering an additional 49 unreported customer orders — including several tied to Karl Studer, a convicted poacher whose name surfaced in the underlying investigation.
The charges filed against Schiermeier alleged that those missing records amounted to improper record-keeping and, in some cases, preparation of false evidence — serious accusations for a taxidermist whose business would have had direct dealings with hunters involved in illegal activity.
The poaching investigation itself was among the more sweeping in recent Idaho history, reportedly exposing a black market hunting tag scheme and incidents of wildlife harassment involving a helicopter. One individual connected to the broader investigation lost his Idaho hunting license for life. For readers following Idaho’s natural resources enforcement landscape, other major criminal trials in the region have similarly tested the courts’ ability to manage complex, evidence-heavy cases.
Defense Challenges Legal Basis for Record-Keeping Requirements
The mistrial was set in motion during cross-examination, when defense attorney Wells pressed a Fish and Game officer on the precise legal authority requiring taxidermists to maintain the types of records at issue in the case.
“Explain to me where in the IDAPA or the Idaho code section, explain to me where it says what information has to be in a record?” Wells challenged the officer on the stand.
The officer began to reference an IDAPA code section in response, but Wells pushed for a more specific answer confined to the two particular code sections at the heart of the prosecution’s theory. Judge Cluff ultimately agreed that the underlying legal questions — specifically, what recording requirements actually apply and how they are to be interpreted — had not been sufficiently resolved before the trial began.
“Unfortunately, there are issues — legal issues — that are involved here that the court needs to resolve with respect to how the recording of new information needs to occur,” Cluff said in concluding remarks.
The procedural breakdown underscores a recurring challenge in wildlife enforcement cases: translating administrative code requirements, such as those found in Idaho’s IDAPA rules, into clear criminal standards that can withstand courtroom scrutiny. Cases involving financial crimes and evidentiary disputes — such as a recent Bannock County case involving alleged cash theft through fraudulent refunds — demonstrate how quickly evidentiary questions can reshape the trajectory of a trial.
What Comes Next
A scheduling conference for a new trial date has been set for May 15, 2026. Before proceedings can resume, Judge Cluff indicated the court must first resolve the outstanding legal questions surrounding Idaho’s taxidermy record-keeping requirements and how they apply to the charges against Schiermeier. The outcome of that conference will determine when, and under what legal framework, the state will be permitted to bring its case before a new jury.
