EL PASO, Texas (AP) - Authorities say a Border Patrol agent shot and killed a suspected human smuggler at a fence that separates El Paso from Ciudad Juarez, Mexico.
The Border Patrol says the agent fired after feeling threatened by the man.
Mexico is demanding an investigation alleging an "excessive use of force."
A border patrol agent says the suspect -- Jose Alejandro Ortiz Castillo -- had been caught crossing the border 28 times since 1999. He died in Mexico shortly after Wednesday night's shooting.
An unidentified agent spotted the suspected trafficker apparently leading two men and a woman through a hole in the border fence just east of downtown El Paso.
The man's brother -- Jesus Castillo -- told reporters that his brother had worked as an immigrant smuggler. But after speaking to investigators, he said his brother worked in construction and occasionally crossed the border for work in El Paso.
