Santiago Villalba Mederos

Jesus Mederos, the older brother of Santiago Mederos, was arrested in May 2017 in Cuernavaca, Mexico. Jesus was responsible for the fatal shooting of 18-year-old Robert Tapia at a Tacoma intersection in October 2006. After the murder he fled to Mexico and spent 12 years on the run before being captured. The FBI hopes the arrest of Santiago's brother will help in finding him. A reward of $100,000 has been offered by the FBI for information that leads to the arrest and extradition of Mederos.

On February 7, 2010, Mederos and six other gang members from the ELS were out driving a stolen van through Tacoma, Washington in search for rival gang members. They were after the gang in retaliation for a shooting that had occurred two days earlier in which an ELS member was badly wounded. They came across 20-year-old Camille Love and her brother 19-year-old Josh Love. Camille was driving while Josh was sat in the passenger seat of the vehicle. They had just left a family dinner and were driving to a friend's house. The siblings were stopped at a traffic light and were inside a red car. Josh was wearing a red coat, and red was the color associated with the rival gang. Mistaking Josh for a rival gang member, Mederos and at least one other gang member opened fire into the vehicle. They fatally shot Camille and seriously wounded Josh. Josh was shot twice and was hit in the arm and on his side. Neither Josh or Camille were associated with any gang.

On March 25, 2010, Mederos and another gang member ransacked a car in an apparent robbery in a South Tacoma alley. They suspected the owner of the car owed the gang money. The duo then got into a fight with three other men who confronted them. Mederos shot at the group of people as he fled on foot and fatally shot 25-year-old Saul Lucas-Alfonso. Lucas-Alfonso again was not associated with any gang.

The leader of the Eastside Lokotes Sureños, Juan Zuniga-Gonzalez, was blamed for the murders. The death of Love led to a crackdown from the Tacoma Police Department against the ELS. Unhappy with Zuniga's leadership and the unwanted attention from Love's murder, four members of the gang who were in prison at the time ordered the murder of Zuniga-Gonzalez. On May 12, 2010, Zuniga-Gonzalez was murdered at his home in Tacoma. 15-year-old Naitaalii Toleafoa and 17-year-old Juan Ortiz drove to Zuniga's home. Ortiz fatally shot Zuniga in the back of the head in his garage. Both suspects then fled to Mexico after the assassination. Toleafoa was captured in 2012 and Ortiz was arrested in Mexico City in August 2016. Both were extradited from Mexico to stand trial for the murder.
