Derrick Washington’s long quest to overturn his 2008 conviction for a 2005 double homicide and armed robbery in Springfield hit a wall when the Superior Court denied his motion for a new trial, this comes nearly two decades after the initial verdict. In a social media post from Hampden District Attorney Anthony Gulluni, details emerged about the court's written decision which was issued in December 2025 after seeing evidence unfold over a three-day hearing which concluded on April 11, 2025, this decision effectively upholds Washington's life sentence.
The court found, after its exhaustive review that ranged over the gamut of the trial record, post-conviction filings, and the witness testimony from the recent hearing, that Washington's bid did not meet the legal bar for a new trial; it particularly pointed out that the defendant did not prove any withheld evidence, or newly found information, could have altered the original outcome of the case. The ruling also addressed and dismissed any gain the defendant sought through claims of ineffective assistance of counsel, alongside any potential impact of fresh evidence that had recently come to light.
In a statement that was part of the district attorney's Facebook post, Gulluni expressed his endorsement of the court's meticulous diligence, saying, "We respect the Court’s careful and thorough review of the record in this case," adding, "The Court’s decision reflects the rigorous legal standards applied in post-conviction review and reaffirms the jury’s verdict, and I thank Assistant District Attorney Katharine Johnston for her diligent work on this matter." The decision reinforces the original jury verdict and supports the work of Gulluni’s office, noting its strong commitment to fair and legally sound proceedings.
The Hampden County District Attorney’s Office said in the Facebook post that it respects the court’s decision and remains committed to upholding lawfully obtained convictions. As a result, Derrick Washington’s sentence is expected to remain in place unless future appeals succeed, a difficult standard under the court’s ruling.
