A Suffolk man entered a plea Wednesday in connection with the murder of a 20-year-old Portsmouth man last year.

Tremayne Laron Johnson, 26, entered an Alford plea to charges of murder by mob, conspiracy and shoot, stab, cut or wound, according to his attorney, Fred Taylor.

A charge of first-degree murder is set to be not prosecuted at the conclusion of his sentencing hearing on Dec. 1, Taylor said.

Johnson was one of three men charged in the Jan. 20, 2015, murder of Donta Williams. Transcripts of police interviews filed with the court indicate the men choked and beat Williams on a pedestrian bridge across a North Suffolk lake before pushing him into the water.

An employee at the Department of Defense complex at Lake View Technology Park, located off College Drive near Interstate 664, spotted Williams’ body in the lake between Burbage and College drives on March 9.

Nathaniel Charles McCoy Jr., 22, is set for a jury trial next week on charges of first-degree murder, murder by mob, conspiracy to commit murder and shoot or stab in commission of a felony.

Kyle Lamar Purvis, 22, pleaded guilty to charges stemming from the attack in May. His sentencing is set for Sept. 14.
