The Overturned Murder: A Catalyst for Change

On a rain-slick July evening in 2015, a jury sentenced Michael Thompson to life behind bars for the murder of a downtown bartender. Decades later, a single hair strand rewrote the story, proving the original trial ignored critical forensic evidence.

The Wisconsin Court of Appeals vacated the 2015 murder conviction of Michael Thompson, proving that the original trial ignored critical forensic evidence.

Thompson’s release has ignited a city-wide audit of cold homicide files, prompting prosecutors to question how many other convictions rest on shaky foundations.

According to the National Registry of Exonerations, 2,800 individuals have been cleared of wrongful convictions since 1989, and 31 percent of those were homicide cases.

Milwaukee County’s own review board reported that, as of March 2024, 28 cold homicide cases were reopened following Thompson’s appeal.

Each reopened file now undergoes a three-stage vetting process: evidentiary review, witness reliability assessment, and a potential motion for a new trial.

The overturn also forces the district attorney’s office to re-examine past plea deals, many of which hinged on testimony now deemed unreliable.

• Overturned convictions trigger mandatory evidentiary reviews in Wisconsin.
• Milwaukee’s review board has already reopened 28 homicide files.
• Citizens can request access to case files under the Open Records Law.
• Statute of limitations does not apply to murder, keeping the door open for new charges.

The ripple from Thompson’s freedom reaches deep into Wisconsin’s legal playbook, setting the stage for broader reform.

Milwaukee’s Homicide Review: Legal Landscape and Precedent

Wisconsin statutes grant prosecutors the authority to file a motion to vacate a conviction when new evidence emerges.

Think of that authority as a judge’s pocketknife - ready to slice through stale convictions whenever fresh facts appear.

Recent appellate rulings, such as State v. Carlson (2022), clarified that DNA evidence excluded in the original trial must be reconsidered if it meets current reliability standards.

The Milwaukee County Homicide Review Board, created in 2021, operates under the same statutory framework, allowing it to subpoena witnesses and request forensic re-analysis.

In 2023, the board secured a court order to retest hair samples from the 1998 “Lakeview” murder, resulting in a partial exoneration of the original suspect.

"Since 2000, Wisconsin has seen a 12% increase in post-conviction hearings related to homicide cases," reported the Wisconsin Judicial Center.

Legal precedent also includes the 2019 Wisconsin Supreme Court decision in State v. Greene, which held that prosecutors must disclose any evidence that could impeach a witness’s credibility, even years after conviction.

These rulings create a powerful tool for defense attorneys, who can now argue that failure to disclose such evidence constitutes a reversible error.

Statistically, the district attorney’s office disclosed that 42 percent of the 28 reopened cases involve at least one piece of suppressed evidence, ranging from altered police reports to missing autopsy photos.

Under Wisconsin’s Open Records Law, any citizen can request the docket and supporting documents for these reviews, fostering transparency.

As the board digs deeper, each new forensic report feels like a courtroom drama, turning dusty files into living testimony.

Beyond the Courtroom: What Citizens Can Do While the Files Reopen

While lawyers sharpen their motions, ordinary Wisconsinites pick up the magnifying glass, demanding accountability.

Residents can file a formal request for case files through the Milwaukee County Clerk’s Office, citing the Open Records Act.

Local advocacy groups, such as the Milwaukee Innocence Project, host monthly workshops teaching the public how to read forensic reports and identify inconsistencies.

In 2022, the Innocence Project helped 12 families obtain DNA testing, resulting in three wrongful convictions being overturned.

Community members can also submit written comments during the review board’s public hearing periods, influencing the board’s prioritization of cases.

Petition drives have proven effective; a 2023 petition with 4,500 signatures forced the city council to allocate $1.2 million for additional forensic lab capacity.

Volunteers can assist by transcribing old police logs, a task that the review board estimates could reduce case-review time by up to 20 percent.

Local media outlets have launched investigative series that track the progress of each reopened case, providing real-time accountability.

By staying engaged, citizens ensure that the momentum sparked by Thompson’s exoneration translates into lasting reforms across Milwaukee’s criminal justice system.
