Agents with the U.S. Customs and Border Protection service are coming under scrutiny for killing two individuals near the border with Mexico in recent weeks.

In San Diego, CA, an illegal immigrant who lived in the United States for 27 years was killed after a border guard shot him with a Taser gun. Anastacio Hernández Rojas, a 42-year-old construction worker and father of five children, was deported to Mexico last week after a run-in with local police. He was trying to re-enter the country when border agents arrested him and prepared to send Hernández back to Mexico. Media accounts say Rojas struggled with border guards, prompting one of them to use a Taser to subdue him. The electric shock allegedly caused Hernández to suffer a fatal heart attack

Following the Hernández controversy, a border patrol officer shot and killed a 15-year-old boy standing on a bridge in El Paso, TX, that straddles the border between the two countries. Authorities claim the boy, Sergio Adrian Hernández Guereca, may have been throwing rocks at officers who were detaining illegal immigrants nearby. He was on the Mexican side of the border when he was shot.
