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.
More than four years after U.S. Border Patrol Agent Robert Rosas was shot and killed near Campo, east of San Diego, one of his killers was ordered to spend decades behind bars.
Marcos Rodriguez-Perez, 26, was sentenced Thursday to 56 years in prison for the July 2009 robbery and murder of agent Robert Rosas, Jr.
The 30-year-old Rosas was tracking suspected undocumented immigrants near the border and called for backup before he was shot four times in the head, once in the neck and three times in the torso.
His body was later found along the Shockey Truck Trail.
Rodriguez-Perez pleaded guilty to charges that he was one of the men who murdered Rosas for his night vision goggles.
Three other defendants in the case have also pleaded guilty. Christian Daniel Castro-Alvarez has been sentenced to 40 years in prison, while Emilio Samyn Gonzalez-Arenazas and Jose Ramirez-Dorantes will be sentenced in November.
One fugitive in the case remains: Jose Juan Chacon-Morales.
Rosas, 30, had served with the Border Patrol for three years. He was survived by his wife and two children.
