ALBEMARLE COUNTY, Va. (WVIR) - Albemarle County detectives have charged a fourth man in connection to a homicide back in July.

On Tuesday, November 14, authorities in Northern Virginia picked up 23-year-old Jose Luis Escobar Umana, who is currently awaiting extradition.

He is charged with second-degree murder in the death of 24-year-old Marvin Joel Rivera Guevara.

Police and rescue crews responded to the 2100 block of East Market Street just before noon on Tuesday, July 4, when a fisherman discovered a dead body along the banks of Moore's Creek.

Detectives ruled the death a homicide, but didn't immediately provide further information. On July 20, Albemarle County police identified the homicide victim as 24-year-old Marvin Rivera-Guevara.

Police arrested 20-year-old Walter Antonio Argueta Amaya in connection to the homicide on September 15. He was charged with second-degree murder.

On September 25, Albemarle police charged two more men in connection to the homicide. Eighteen-year-old Eduardo Zelaya of Manassas and 18-year-old Juan Carlos Argueta of Charlottesville both face second-degree murder charges.

Investigators believe that some of the suspects may have affiliation with the gang MS-13, though police have said the victim, Rivera-Guevara, does not appear to be connected with a gang.

The homicide remains under investigation.
