ALBEMARLE COUNTY, Va. (WVIR) - A third man involved in a murder in Albemarle County pleaded guilty to charges in a court hearing on Tuesday morning.

Investigators say 21-year-old Walter Antonio Argueta Amaya was one of four men who stalked, abducted and killed an Albemarle County man as part of a gang rivalry.

Amaya was charged with first-degree murder and abduction of 24-year-old Marvin Rivera-Guevara, whose body was found in Moores Creek near the Woolen Mills neighborhood on July 4, 2017. Investigators believe Amaya and the three other men who were charged are a part of the MS-13 gang.

Amaya pleaded guilty to first-degree murder, gang participation, murder by mob, and abduction.

In court on Tuesday, August 21, the commonwealth said Guevara allegedly threw up a rival gang sign to the group. Several days later, Amaya and several other men carried out what investigators believe to be a planned murder, since Amaya had photos of Rivera-Guevara on his phone. Prosecutors said the four men spotted the victim near a pizza shop, followed him, and forced him out of his car.

According to investigators, Amaya and the other suspects used a machete and other sharp weapons to carry out the attack. Investigators said the body was completely disfigured and contained more than 100 slashing wounds. Prosecutors said the machete was used until it was broken by force. They say the men then burned the victim's car.

Eduardo Zelaya pleaded guilty to murder by mob on August 15. The 19 year old is facing between 23 and 31 years in prison and is a known MS-13 gang member. The next day, Juan Carlos Argueta - another known MS-13 member - pleaded guilty to the same charges as Zelaya.

Charges against a fourth suspect - Jose Luis Escobar Umana - are still pending.
