The Case
What Happened — and What Remains Disputed
Kersten Kischnick was killed in Florida in 1987. Dieter Riechmann was convicted of murder in 1988 and maintains that he did not commit the crime. This page places documented procedural events in context and distinguishes them from issues that remain disputed in the records reviewed.

Overview
Key Milestones
On October 25, 1987, Kersten Kischnick was killed by a gunshot in Florida. The prosecution relied, among other things, on circumstantial evidence, forensic findings, firearms and ammunition, an alleged financial motive, and witness testimony. Riechmann, by contrast, says that an unknown man fired the shot after being asked for directions.
In 1988, a jury found Riechmann guilty of murder; in November of that year, he was sentenced to death. He has maintained that he did not commit the crime and has raised challenges to the conviction, the evidence, and the proceedings in various cases since then.
The conviction itself was not vacated in 1996. The court vacated the death sentence and ordered a new sentencing proceeding. In 2010, a life sentence was imposed.
Further motions and appeals followed. In the most recent appellate proceeding reviewed here, the Third DCA denied Riechmann’s motion for rehearing and rehearing en banc on June 4, 2026. On June 26, 2026, the court issued its mandate, ending this regular phase of the appeal before the Third DCA.

The Evidence
What the Conviction Was Based On
The case did not rest on a single piece of evidence, but on a combination of circumstantial evidence and witness testimony.
The prosecution relied, among other things, on gunshot residue on Riechmann’s hands, the interpretation at the time of bloodstains in the vehicle, firearms and ammunition, insurance policies and reciprocal wills as a possible financial motive, and witness testimony.
Walter Smykowski, a former cellmate of Riechmann’s, played an important role. He reported alleged statements and reactions by Riechmann that the prosecution presented as incriminating and as evidence of a financial motive.
None of the three firearms seized from Riechmann was identified as the murder weapon. Several forensic findings, witness statements, and issues concerning the disclosure of records were later challenged again in subsequent proceedings.
View the Individual Disputed IssuesA Voice from the Original Jury
How Close Did One Juror Consider the Evidence?
A juror from the original trial later said in the documentary “Todesstrafe für eine Lüge” that, in his personal view, the evidence probably would not have been sufficient for a conviction if Dieter Riechmann had not testified himself.
He said that only a few additional unresolved doubts would, in his view, have been enough to prevent a conviction.
Immediately beforehand, the documentary shows that Riechmann’s own testimony subjected him to lengthy cross-examination. His background, prior convictions, and other personal circumstances were also raised before the jury. Looking back, the juror said that Riechmann’s statements and demeanor also influenced his assessment.

Timeline
Overview of Procedural Milestones
The timeline summarizes key steps documented in the records reviewed. It is not a complete review of the case file. Disputed issues are addressed separately on the page about questions surrounding the conviction.
Rehearing and mandate
After a motion for rehearing was initially treated as untimely, the court recognizes in January 2026 that it had been timely filed under the filing rule applicable to prisoner mail and reinstates it. After further filings by both sides, the court denies both rehearing and rehearing en banc on June 4, 2026. The court issues its mandate on June 26, 2026, ending this regular appellate stage before the Third DCA.
Third DCA affirms challenged decisions
In October 2025, the Third DCA affirms the challenged decisions of the trial court.
Further petition denied

Life sentence imposed
After the further proceedings, the new sentencing takes place: Dieter Riechmann is sentenced to life imprisonment.

2002–2003 – Further post-conviction hearing
During a multi-day court hearing, the court considers, among other things, newly presented witness testimony, an alleged confession by a third party, and further allegations concerning Walter Smykowski. In 2003, the court again declines to overturn the conviction.
Florida Supreme Court affirms decision
The Florida Supreme Court affirms the 1996 decision. The new sentencing proceeding remains ordered, while the challenges to the conviction do not result in a new trial.
New sentencing proceeding ordered
After an extensive court hearing, the request to overturn the conviction is denied. The death sentence is nevertheless vacated, and a new sentencing proceeding before a new judge and a new jury is ordered.

International Dimension
Germany’s Submission in the Proceedings
In 2005, Germany filed its own submission with the Florida Supreme Court. It focused in particular on how evidence had been obtained in Germany and then used in proceedings in which a death sentence had originally been imposed.
Germany stated, among other things, that promised formal mutual legal assistance requests had not been received and that, in a proper mutual legal assistance process, assurances would have been required that the evidence would not be used to seek or impose the death penalty.
The submission supported Riechmann’s appeal at the time and, from Germany’s perspective, sought a new trial or at least limits on any new sentencing proceeding. The court’s acceptance of the submission did not mean that it adopted Germany’s entire legal analysis or found Riechmann innocent.

Frequently Asked Questions
Why was the death sentence vacated?
The court found several problems in the original sentencing proceedings. These included inadequate defense performance during that phase, undisclosed favorable information, and improper prosecutorial involvement in the original sentencing order. Those findings led to a new sentencing phase, not to the conviction being vacated.
Was the evidence conclusive?
The conviction rested on a combination of circumstantial evidence, forensic findings, and witness testimony. None of the firearms seized from Riechmann was identified as the murder weapon. Years later, a former juror said that, in his personal view, the evidence probably would not have been sufficient for a conviction without Riechmann’s own testimony. That is the juror’s retrospective assessment, not a court finding.
Why do disputed issues remain?
Later proceedings challenged, among other things, witness testimony, undisclosed records, and the evidentiary value of forensic findings. Some issues were reviewed on the merits, while other later claims failed in whole or in part because of procedural rules. The individual issues are presented separately on the “Questions About the Conviction” page.
