U.S. Border Patrol agents file past a portrait of fellow agent Robert Rosas before the start of his memorial service on July 31, 2009 in El Centro.
A fourth suspect was arrested Monday in the case of a Border Patrol agent’s 2009 death, leaving but one suspect at large, the United Stated Department of Justice and Department of Homeland Security confirmed Wednesday.
Marcos Rodríguez-Perez was one of three men who allegedly shot and killed Robert W. Rosas, Jr. on July 23, 2009 while he was on a routine patrol in Campo, Calif.
The lone looming suspect is José Juan Chacón-Morales, whom authorities consider to be armed and “extremely dangerous.”
Chacón-Morales and José Luis Ramirez-Dorantes are suspected of serving as armed lookouts in Mexico while Rodríguez-Perez, Emilio Samyn Gonzales-Arenazas and Christian Daniel Castro-Alvarez crossed the border and lured Rosa from his vehicle to rob him.
The three men allegedly shot Rosas multiple times before fleeing to Mexico with his firearm, gear bag, handcuffs and night vision goggle, according to court documents.
“Although the recent arrest by Mexican authorities was a tremendous step in seeking justice on behalf of Agent Rosas,” said United States Attorney Laura E. Duffy in a media release, “our work on this case is far from complete.”
Castro-Alvarez entered a guilty plea on Nov. 20, 2009 and, pursuant to a plea agreement, entered a guilty plea. He was sentenced to serve 480 months in custody.
Chacón-Morales, Ramirez-Dorantes, Rodríguez -Perez, face five charges, including murder of a federal officer committed in perpetration of a robbery and unlawful confinement.
Chacón-Morales, 26, is described as being 5-foot-9, 175 pounds with black hair and brown eye. The Mexico native has tattoos on his back, chest and left shoulder.
Authorities are offering an up to $100,000 reward and ask that anyone with information contact a local FBI office, nearest American Embassy or Consulate, or call 1-877-EZ 2 Tell.
