Background
Nosakhare Onumonu was convicted by a Wayne County jury in July 2015 of the 1999 murder of 84-year-old Helen Klocek, who was found strangled and beaten in a Detroit alley. The case went cold for more than a decade until a Kevlar glove recovered from Klocek’s burned vehicle was submitted for DNA analysis in 2011, yielding a match to Onumonu’s profile in the CODIS database. Onumonu was sentenced to life in prison, and the Michigan Court of Appeals affirmed his convictions on direct appeal in 2017.
In subsequent years, Onumonu pursued multiple avenues of post-conviction relief. Through FOIA requests, he obtained documents concerning police consideration of alternative suspects and raised claims that the prosecution suppressed exculpatory evidence in violation of Brady v. Maryland. He also obtained an affidavit from retired Detroit Police Sergeant Henry Ellis suggesting the Kevlar glove may not have existed or been documented until years after the crime. Additionally, Onumonu argued that evidence of his employment history constituted newly discovered evidence undermining the prosecution’s theory that his connection to PDC Glass placed him in proximity to the murder scene and explained his DNA on the glove.
After a complex procedural history that included a prior interlocutory appeal (Onumonu II, 2024) and an evidentiary hearing, the Wayne Circuit Court granted Onumonu’s motion for relief from judgment and ordered a new trial. The prosecution appealed by leave granted.
The Court’s Holding
The Michigan Court of Appeals reversed the trial court’s grant of a new trial, holding that Onumonu failed to satisfy the requirements of MCR 6.508(D) for relief from judgment. The panel found that the trial court’s key factual findings were clearly erroneous. Most critically, the court found that Onumonu already knew about the alternative suspects before receiving the FOIA evidence — a fact demonstrated by his own direct appeal, in which he argued ineffective assistance of counsel for failing to present evidence about those same suspects. Because he was aware of the alternative suspects before his FOIA request, that evidence was not “newly discovered” and could not establish either good cause under MCR 6.508(D)(3)(a) or a Brady violation.
The court similarly rejected the claims based on Sergeant Ellis’s affidavit concerning the glove. Onumonu had raised questions about irregularities in the glove’s documentation on direct appeal, meaning the underlying doubts were not newly discovered. Moreover, the court found Ellis’s affidavit factually unreliable: trial testimony from evidence technician Sergeant Babcock established that the glove was recovered from the vehicle on March 8, 1999 — contradicting Ellis’s assertion that it was not documented until 2010 — and an evidence technician report from that same date listed the glove.
The court also rejected Onumonu’s employment-history claim, reasoning that a defendant necessarily has knowledge of his own employment history, rendering that evidence neither newly discovered nor subject to Brady disclosure. Furthermore, the additional employment records showed only that Onumonu had other employers in 1999; they did not affirmatively disprove that he worked for PDC Glass during the relevant period. The court additionally found no actual prejudice under MCR 6.508(D)(3), noting that the alternative suspects were not meaningfully supported by the evidence — one was a white male contradicting the eyewitness description, and the other was linked only by a witness’s opinion about propensity rather than any direct connection to the crime.
Key Takeaways
- Evidence raised in a prior ineffective-assistance claim on direct appeal cannot later qualify as “newly discovered” under MCR 6.508(D) or Cress — awareness of an issue at any prior stage forecloses the newly-discovered-evidence theory.
- A Brady suppression claim fails when the defendant demonstrably knew of the allegedly suppressed information before or at trial, because suppression requires that the prosecution withheld evidence the defendant did not otherwise possess.
- A defendant’s own employment history is not subject to Brady disclosure; the prosecution has no duty to investigate and produce records that the defendant can independently obtain.
- To establish actual prejudice under MCR 6.508(D)(3), the alternative evidence must meaningfully undermine the conviction — speculation about other suspects’ propensity, without direct inculpatory evidence linking them to the crime, is insufficient.
Why It Matters
This decision reinforces the strict gatekeeping function of Michigan’s post-conviction relief rule, MCR 6.508(D), particularly the requirement that defendants clearly delineate when and how they first learned of evidence they claim was suppressed or newly discovered. Courts will look to the full record — including prior appellate filings — to determine whether a defendant’s claim of ignorance is credible. Defendants who raise issues on direct appeal, even under a different legal theory, risk foreclosing those same factual issues in later post-conviction proceedings.
The case also illustrates the evidentiary burden that expert or lay affidavits must clear to support post-conviction relief. An affidavit from a former law enforcement officer offering procedural opinions will be weighed against the contemporaneous trial record, and inaccuracies — such as Sergeant Ellis’s incorrect claim that the glove was not documented until 2010 — can fatally undermine a motion for a new trial rather than support it.
