Commonwealth v. Bateman · Massachusetts Supreme Judicial Court · February 20, 2026 · No. SJC-10079

Summary

The Massachusetts Supreme Judicial Court affirmed the denial of Dennis M. Bateman's second motion for a new trial following his convictions for two counts of murder in the first degree. The court rejected claims involving the nondisclosure of an audio recording, alleged anomalies in recordings of a police interview, and ineffective assistance of counsel. It concluded that the undisclosed material was not prejudicial and that the remaining claims did not warrant relief.

Jurisdiction
Massachusetts Supreme Judicial Court
Decision date
February 20, 2026
Docket number
SJC-10079
Procedural posture
The defendant appealed from the Superior Court's denial of his second motion for a new trial in a first-degree murder case. The appeal was before the Supreme Judicial Court pursuant to Mass. Gen. Laws c. 278, § 33E.
Standard of review
The denial of a motion for a new trial is reviewed for a significant error of law or abuse of discretion, with special deference to a motion judge who was also the trial judge. Newly discovered evidence claims are reviewed for abuse of discretion or other error of law, with deference to factual findings based partly or wholly on testimonial evidence unless clearly erroneous. In a first-degree murder case, ineffective-assistance claims are reviewed for a substantial likelihood of a miscarriage of justice, with particular deference when the motion judge was also the trial judge.

Questions Presented

  1. Whether the Commonwealth's failure to disclose the first segment of an audio recording of potential witness Mark Whalen's police interview prejudiced the defendant and required a new trial.
  2. Whether expert opinions identifying anomalies in recordings of the defendant's police interview constituted newly discovered evidence that cast real doubt on the justice of the convictions.
  3. Whether trial counsel was ineffective for failing to interview or call Allison and Kenneth Hamilton, and whether prior appellate counsel was ineffective for failing to raise that claim.
  4. Whether the asserted errors required evidentiary hearings or relief based on cumulative prejudice.

Holdings

  1. Although the Commonwealth was required to disclose the undisclosed interview segment, the defendant failed to establish prejudice because the segment was materially cumulative of the disclosed written statement, did not materially strengthen a possible alibi or Bowden defense, and would not reasonably have affected the verdict in light of the overwhelming evidence of guilt.
  2. The expert opinions concerning alleged anomalies in recordings of the defendant's police interview did not warrant a new trial because the evidence was reasonably discoverable before the defendant's first new-trial motion and, in any event, did not cast real doubt on the justice of the convictions.
  3. Trial counsel's failure to interview or call Allison and Kenneth Hamilton did not create a substantial likelihood of a miscarriage of justice because their testimony would not have materially contradicted the prosecution evidence or likely influenced the verdict.
  4. Because trial counsel was not ineffective, prior appellate counsel was not ineffective for failing to argue that trial counsel was ineffective.

Key quotations

A defendant seeking a new trial based on undisclosed evidence has the burden to show that he or she was prejudiced by the nondisclosure. (13-14)
To prevail on his claim that he is entitled thereby to a new trial, the defendant must show that "the evidence is in fact newly discovered; the newly discovered evidence is credible and material; and the newly discovered evidence casts real doubt on the justice of the conviction[s]" (22-23)
We review "claims of ineffective assistance of counsel in cases of murder in the first degree for a substantial likelihood of a miscarriage of justice." (29)

Factual background

The defendant was convicted of murdering Brandy Waryasz and her viable unborn child at a gasoline station in Deerfield in 2005. The prosecution presented evidence including the defendant's distinctive van at the station, his DNA on the ligature used to strangle Waryasz, incriminating statements to police and a fellow detainee, and possession of substantial cash after the murders. The defendant's second new-trial motion relied on a previously undisclosed portion of a witness interview, expert claims that recordings of the defendant's police interview showed signs of manipulation, and the failure to investigate or call two witnesses who made a U-turn at the station around the time of the murders.

Procedural history

The defendant was convicted in 2007 of two counts of murder in the first degree and armed robbery. In 2023, the Supreme Judicial Court affirmed the murder convictions and denial of the defendant's first motion for a new trial but vacated the duplicative armed-robbery conviction. While the prior consolidated appeal was pending, the defendant filed a second motion for a new trial asserting nondisclosure of an audio recording segment, newly discovered evidence concerning alleged manipulation of police-interview recordings, and ineffective assistance of counsel. The Superior Court denied the motion after an evidentiary hearing on the audio-recording issue, and the Supreme Judicial Court affirmed.
