A Portsmouth man told police he “took an object and choked” a man whose body was later discovered in a North Suffolk lake, according to court documents.

Nathaniel Charles McCoy Jr., 21, faces charges of first-degree murder; shoot stab, cut or wound; and conspiracy to commit a felony.

His alleged involvement in the death of Donta L. Williams, 22, is described in an affidavit filed in Suffolk General Court, after he was formally served with arrest warrants in Western Tidewater Regional Jail on Thursday. McCoy was extradited from Michigan.

McCoy, scheduled for an arraignment hearing on Friday, allegedly admitted to police that while he proceeded to choke Williams, his two “co-conspirators struck the victim multiple times,” causing blunt-force trauma, according to the criminal complaint.

Kyle Lamar Purvis, 21, of Portsmouth, and Tremayne L. Johnson, 25, of Suffolk, both face the same charges as McCoy. The medical examiner ruled the death was a homicide.
