[Ed. – Something this article doesn’t indicate is which side of the border the shooters approached from. It also doesn’t say if the targets — hired security guards, who were working for a Mexican company — are Mexican or U.S. citizens. They could have been either, although presumably of Mexican origin and native Spanish speakers.]
A shootout at a border wall construction site near San Diego that wounded two Mexican security guards last summer is now under FBI investigation, according to private contractors and government documents obtained by The Washington Post.
The incident, which has not been publicly disclosed, occurred on the night of July 1 east of the San Ysidro border crossing, when Mexican security guards came under fire while protecting materials and equipment for Texas-based Ultimate Concrete, according to a U.S. Army Corps of Engineers report.
One of the guards was shot in the lower right buttock, and another suffered a light shoulder wound. The assailants were not identified, but security camera footage of the incident showed that a group of six or seven gunmen approached a job site where U.S. contractors had been installing steel barriers during the day.
“Three men in the vicinity of the border wall immediately opened fire” on the two security contractors, according to the Army Corps account.
