On September 25, 2000, while on routine patrol, Deputy Schapp and his partner initiated a traffic stop on a full size van. Before either deputy was able to exit the patrol car, the sliding door of the van flew open and illegal alien Emigdio Preciado began firing an assault weapon at the patrol vehicle, striking Deputy Schapp in the forehead. Twenty-one 7.62 shell casings were recovered at the scene.
Preciado remains at large today and is believed to be in Mexico. The three passengers in the van have pled guilty to assault on a police officer.
Deputy Schapp has returned to very limited duty, currently in a training unit giving "sensitivity" training.
On August 9, 2002, Ranger Eggle and three U.S. Border Patrol officers responded after Mexican Police reported that two armed fugitives had fled across the border into the United States at Organ Pipe Cactus National Monument. A border patrol helicopter gave chase and directed Eggle and the other officers to the location where three suspects had ditched their vehicle. The American officers pursued the fugitives on foot as they ran into nearby bushes. One of the Mexican nationals was caught, and during the attempt to apprehend the other two, Eggle was ambushed and shot by one of the suspects with an AK-47. Eggle was hit below his bullet-proof vest and died at the scene before the emergency helicopter arrived.
The shooter, Panfilio Murillo Aguila, was shot to death by Mexican officers standing on the Mexican side of the border.
