Jeffrey Weinhaus Case: Attorney Nick Hergott Files Petition with Missouri Supreme Court

Summary: Attorney Nick Hergott, alongside Attorney Sean O’Brien, filed a Petition for Writ of Habeas Corpus with the Missouri Supreme Court seeking the release of Jeffrey “Jeff” Weinhaus and the reversal of his wrongful convictions. The petition argues that critical exculpatory evidence was withheld from the jury, including evidence related to former Missouri State Highway Patrol Sergeant Henry Folsom’s PTSD and documented misperception issues.


Why Are Attorneys Fighting for Jeffrey Weinhaus’s Release?

Attorneys Nick Hergott and Sean O’Brien believe Jeff Weinhaus was wrongfully convicted after a 2012 shooting involving former Missouri State Highway Patrol Sergeant Henry Folsom.

The petition filed with the Missouri Supreme Court argues that:

  • Exculpatory evidence was withheld
  • The jury never heard key information about Folsom’s mental health
  • Evidence existed showing Folsom was prone to misperceiving threats
  • The shooting and investigation raise serious concerns about the integrity of the conviction

With support from Miracle of Innocence, the legal team is seeking to vacate Weinhaus’s convictions and secure his freedom.

What Happened in the Jeffrey Weinhaus Case?

Former Missouri State Highway Patrol Officer Henry Folsom arranged to meet Jeffrey Weinhaus at the MFA gas station on K Highway near St. Clair, Missouri. According to court filings, Folsom told Weinhaus he would return computer equipment that had previously been seized from his home.

Within seconds of exiting his vehicle in the parking lot, Folsom shot Weinhaus multiple times in the head, neck, and chest.

Witnesses later described the shooting as looking like an execution. Despite suffering catastrophic injuries, Weinhaus survived.

Folsom claimed he shot Weinhaus in self-defense after believing Weinhaus was attempting to draw a firearm that was legally holstered. Based largely on that testimony, Weinhaus was convicted of assaulting an officer and armed criminal action and sentenced to 30 years in prison.

What Evidence Was Allegedly Withheld From the Jury?

The habeas petition alleges that the jury was never told several critical facts about Henry Folsom, including that:

  • He suffered from long-term, symptomatic PTSD
  • He was taking medication related to that condition
  • The Missouri State Highway Patrol ultimately determined he was unfit for duty
  • One fitness-for-duty evaluation reportedly found he was prone to misperceiving threats

According to the petition, one evaluation described scenarios where a person reaching for a wallet could be perceived by Folsom as reaching for a gun.

The petition argues this information directly impacted the credibility and reliability of Folsom’s account of the shooting.

How Does This Relate to Other Wrongful Conviction Cases?

The petition also notes that Henry Folsom was involved in the investigation and murder conviction of Donald Nash.

In 2020, the Missouri Supreme Court vacated Nash’s wrongful conviction.

Attorneys for Weinhaus argue that this history raises additional concerns about the reliability of the investigation and testimony involved in Jeff Weinhaus’s case.

Why Does This Case Matter?

Wrongful conviction cases often involve more than what appears in the original trial record.

When evidence is withheld, juries may never hear information that could significantly affect the outcome of a case. Habeas petitions and post-conviction investigations are critical tools for uncovering new evidence, challenging constitutional violations, and pursuing justice after a conviction.
