I must have missed the story about this incident.
Do you have any more information?
It's been around for awhile. Two Border Patrol Agents in the El Paso area, stopped a drug smuggler with a gazillion pounds of dope in his van.
He pulled what looked like a gun. They fired. He ran, wounded, into Mexico. They did not know they hit him. Well, the rest is history.
In the trial, the U.S. Attorney said the drug smuggler was "going home" not smuggling drugs.
