Hernandez died three days after being attacked by immigration officials with a taser device, after he was detained for attempting to cross the border illegally.
According to the report, Hernandez may have consumed meth-amphetamines. That, plus the fact that he had high blood pressure, may have contributed to his death.
Hernandez had lived and worked in the United States for 26 years, and was recently deported to Mexico following a traffic violation. At the time of his death, he was attempting to re-enter the U.S. so he could reunite with his wife and five children.
