Federal Child Porn Case Against Jeffrey Koistinen Advances

Repo Buzz – July 22, 2025 — The federal child exploitation case against Jeffrey Allen Koistinen, a 58-year-old Watertown, South Dakota native, is advancing under a newly issued trial scheduling order from the U.S. District Court for the District of Arizona. Koistinen faces multiple felony charges stemming from allegations of attempted production and receipt of child pornography, with prosecutors citing extensive digital evidence and international activity.

The latest development in the high-profile case came on May 9, 2025, when District Judge Angela M. Martinez granted the seventh motion to continue the trial, citing concerns that denying additional preparation time for the defense “is likely to result in a miscarriage of justice.” The order lays out a detailed roadmap for the pre-trial phase and trial proceedings, designed to ensure the case moves toward resolution without further delay.

Updated Trial and Plea Schedule:

• Plea Deadline: August 15, 2025, by 3:00 p.m.
  (The court reserves the right to reject any plea submitted after this time, except a plea directly to the indictment.)

• Jury Trial Date: September 3, 2025, at 9:30 a.m.

The order reinforces the Court’s intent for a “prompt disposition of this matter” and establishes hard deadlines for all key pre-trial activities:

• Discovery & Disclosures Deadline: May 23, 2025
  (Includes expert testimony, defense notices, and government evidence.)

• Pre-Trial Motions Deadline: June 6, 2025
  (Late filings require Court permission and good cause. This deadline will not shift even if future continuances are granted.)

• Final Continuance Motions Deadline: August 18, 2025, by 5:00 p.m.
  (Attorneys must notify the Court via email if no motion is forthcoming and provide the expected number of trial days.)

Background of the Case

Koistinen was first arrested in August 2023 in Los Angeles, caught attempting to board an international flight to the Philippines—in direct violation of his bond conditions. Prosecutors allege Koistinen had been actively engaged in online chats involving the exchange of child pornography, including payments via Remitly to individuals overseas in return for sexually explicit material involving minors.

He is currently facing:

• Multiple counts of attempted receipt of child pornography

• Charges of sexual exploitation of a minor

• Possession of explicit materials involving prepubescent children

Federal prosecutors argue that Koistinen is a flight risk, citing his previous attempt to leave the U.S., ownership of overseas property, and substantial financial resources. The government has also alleged ties to an illegal marijuana operation, further complicating his criminal profile.

The case was reassigned to Judge Angela Martinez in August 2024, and she has since overseen the pretrial process with strict compliance expectations. Koistinen remains in federal custody.

What’s Next?

With the September 3 trial date approaching, the government and defense have limited time to finalize motions, disclosures, and plea considerations. Judge Martinez has made clear that the Court will not tolerate further delays without substantial justification. Whether Koistinen will proceed to trial or enter a plea remains uncertain, but the next major deadline—August 15—may provide clarity.

The U.S. Attorney’s Office in Tucson continues to prosecute the case, while Koistinen is represented by attorney Nicholas M. Loncar of Tucson Defenders.

As the court navigates complex digital evidence, international transactions, and child exploitation allegations, the public and legal observers alike will be watching closely for the outcome of this deeply troubling case.
