Read the full case

Background

  • Raymond Mayrant was convicted in New York state court of second-degree murder and attempted second-degree murder stemming from the fatal shooting of Elvira Brown and attempted murder of Diamond Dunn.
  • Mayrant's relationship with Dunn was volatile, involving multiple breakups and domestic incidents, culminating in the January 3, 2013 shootings in Dunn's apartment.
  • He was arrested in Ohio after fleeing the state, indicted by a grand jury, convicted at trial, and sentenced to 50 years-to-life.
  • Mayrant, proceeding pro se, filed a federal habeas petition under 28 U.S.C. § 2254, challenging his convictions on several grounds, including claims of a defective felony complaint, improper juror discharge, a verdict against the weight of the evidence, and a violation of the Confrontation Clause.
  • The District Court reviewed Magistrate Judge Moses’s recommendation de novo, as Mayrant timely objected to findings on all but the weight-of-the-evidence claim.
  • The District Court adopted the Magistrate’s recommendations, denying the petition in full, finding most claims procedurally barred and all claims meritless.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Defective Felony Complaint Complaint lacked reasonable cause and jurisdiction. Claim was not raised on direct appeal; probable cause clear. Procedurally barred and meritless
Juror Discharge Prospective juror was improperly dismissed, harming impartiality. Court properly dismissed juror based on voir dire doubt. No federal question; claim denied
Weight of the Evidence Verdict contradicted the credible evidence, mainly his testimony. Claim is a matter of state, not federal, law. Not cognizable on habeas review
Confrontation Clause - Stipulation Allowing stipulation on cause of death without live medical examiner violated his rights. Claim is procedurally barred; stipulated evidence was strategic, no violation. Procedurally barred, no constitutional error

  • Melendez-Diaz v. Massachusetts, 557 U.S. 305 (stipulations may waive confrontation rights if voluntarily made)

  • Irvin v. Dowd, 366 U.S. 717 (Sixth Amendment assures trial by impartial jury)
