More than two decades after the murder of Jason Mizell — Jam Master Jay, the DJ who helped bring hip-hop to the world — a Brooklyn federal judge has quietly dismantled a jury's verdict, acquitting Karl Jordan Jr. of the killing that haunted a community and a culture for years. The reversal, granted by U.S. District Judge LaShann DeArcy Hall in late 2025, turned on whether the evidence truly bore the weight prosecutors placed upon it — and she concluded it did not.

Judge Acquits Karl Jordan Jr. in Run-DMC's Jam Master Jay Murder Case
Jam Master Jay (Jason Mizell) was killed in his Queens recording studio in 2002; Karl Jordan Jr. remains incarcerated on drug charges.
The case that stumped hip-hop for decades now splits in two
Mark
Why would a judge overturn a jury conviction nearly two years after the fact? That's unusual, isn't it?
Mimi
It is. What happened here is the judge exercised what's called a judgment of acquittal—essentially saying the evidence, even taken in the government's favor, wasn't enough to prove guilt beyond a reasonable doubt. The jury had convicted, but the judge looked at the record and disagreed.
Luke
But there was an eyewitness who testified Jordan did it. How does a judge just erase that?
Mimi
An eyewitness testimony is evidence, but it's not automatically conclusive. The defense argued it wasn't corroborated by other facts in the case. The judge apparently found that argument persuasive.
Mark
So the eyewitness could have been mistaken, or lying?
Mimi
The judge's ruling doesn't tell us which. It just says the totality of evidence didn't meet the legal threshold for conviction.
Luke
And Jordan walks free from the murder charge?
Mimi
From the murder charge, yes. But he's still in prison on drug charges from a separate case, years after the killing.
Mark
So this acquittal doesn't actually change his immediate circumstances much.
Mimi
Not in terms of his incarceration, no. But legally and historically, it's significant. The case that defined an era of hip-hop mystery just fractured into two different outcomes.
Luke
What about Washington, the co-defendant? He's still convicted?
Mimi
The judge denied his request for acquittal or a new trial. So yes, his conviction stands.
The Pulse
- A jury's guilty verdict — delivered nearly two years ago — has been erased by a single judge who found the evidence insufficient to sustain a murder conviction.
- The case had always been fragile at its core, resting heavily on one eyewitness who claimed to have seen Jordan fire the fatal shots inside a Queens recording studio on October 30, 2002.
- Jordan's legal team argued the prosecution never truly closed the gap between accusation and proof, and the judge's ruling validated that argument in full.
- Despite the acquittal, Jordan walks no freer — he remains behind bars awaiting trial on unrelated drug charges, complicating any sense of resolution for his family.
- Co-defendant Ronald Washington was denied both acquittal and a new trial, meaning the same evidence now produces two entirely different legal fates.
- The murder that silenced one of hip-hop's founding voices now yields not closure, but a fractured legal aftermath that may yet invite further appeals and scrutiny.
More than two decades after the murder of Jason Mizell — Jam Master Jay, the DJ who helped bring hip-hop to the world — a Brooklyn federal judge has quietly dismantled a jury's verdict, acquitting Karl Jordan Jr. of the killing that haunted a community and a culture for years. The reversal, granted by U.S. District Judge LaShann DeArcy Hall in late 2025, turned on whether the evidence truly bore the weight prosecutors placed upon it — and she concluded it did not. Yet justice, as it so often does, arrives unevenly: Jordan remains incarcerated on separate charges, and his co-defendant Ronald Washington's conviction stands untouched.
On a Friday in late 2025, a Brooklyn federal judge quietly rewrote the legal history of one of hip-hop's most enduring mysteries. U.S. District Judge LaShann DeArcy Hall granted Karl Jordan Jr. an acquittal on murder charges — overturning a jury conviction handed down nearly two years earlier — in the 2002 killing of Jam Master Jay, born Jason Mizell, the pioneering DJ of Run-D.M.C.
The case against Jordan had always leaned heavily on a single eyewitness who testified to seeing him fire the fatal shots inside Mizell's Queens recording studio on October 30, 2002. Prosecutors framed the killing as revenge over a failed drug deal. But Jordan's legal team argued the government's evidence simply did not meet the burden of proof, and Judge DeArcy Hall agreed, siding with the defense in her ruling.
Mizell had been a foundational figure in hip-hop — a member of the group that brought the genre to mainstream audiences through songs like "It's Tricky" and a genre-crossing collaboration with Aerosmith on "Walk This Way." His unsolved murder became one of the culture's most stubborn wounds, lingering for over two decades before charges were finally brought.
The acquittal, however, does not mean freedom. Jordan remains incarcerated on separate drug charges unrelated to the murder. His attorney, John Diaz, expressed relief that justice had been served, but the reality is more complicated than the legal victory suggests.
Meanwhile, co-defendant Ronald Washington fared differently. The same judge denied his motions for either acquittal or a new trial, leaving his conviction intact. From a single trial and a shared body of evidence, two men now carry two entirely different legal fates — one murder charge erased, one upheld — as the long, unresolved story of Jam Master Jay's death enters yet another uncertain chapter.
On a Friday in late 2025, nearly two decades after Jam Master Jay was shot dead in his Queens recording studio, a Brooklyn federal judge undid a jury's conviction. U.S. District Judge LaShann DeArcy Hall granted Karl Jordan Jr. an acquittal on the murder charges—a reversal that came almost two years after the jury had found him guilty of killing the pioneering DJ.
Jordan's case had rested on a single eyewitness account. Someone testified they saw him fire the fatal shots on October 30, 2002, in the studio where Jam Master Jay—born Jason Mizell—worked the turntables. Prosecutors had argued the motive was revenge over a failed drug transaction. But Jordan's legal team mounted a different reading of the evidence. They contended that what the government presented simply did not prove he pulled the trigger. The judge agreed. In her ruling, she sided with the defense.
Jason Mizell had been the third member of Run-D.M.C., the group that opened hip-hop to mainstream audiences in the 1980s. Their songs—"It's Tricky," a reimagined "Walk This Way" with Aerosmith—became cultural touchstones. Mizell's death in 2002 became one of hip-hop's most stubborn unsolved mysteries, a case that lingered without resolution for years.
Jordan's acquittal does not mean freedom. He remains in custody, awaiting trial on drug charges unrelated to the murder—offenses from years after Mizell's death. His attorney, John Diaz, released a brief statement expressing relief that "justice was served" for his client and family, but the practical reality is more complicated. The murder conviction has been erased, yet Jordan stays behind bars.
The same judge who acquitted Jordan denied a parallel request from the co-defendant, Ronald Washington. Washington sought either an acquittal or a new trial, but the court rejected both motions. His conviction stands. The case that stumped investigators and the hip-hop world for more than two decades now splits into two separate legal outcomes—one man freed from murder charges, one still convicted, both outcomes flowing from the same trial and the same evidence.
