Arrest shows challenge of keeping rogues off Border Patrol

HOUSTON (AP) – The arrest of a Border Patrol supervisor on allegations that he killed four women is calling new attention to the agency’s problems keeping rogue officers off its force.

The issue emerges as the agency faces intense pressure to hire thousands more agents to help with President Donald Trump’s crackdown on illegal immigration.

The Border Patrol has struggled for many years to hire enough agents. Many jobs on the force require living in remote desert towns along the U.S.-Mexico border. Applicants must pass a detailed background check and a polygraph exam.

Juan David Ortiz worked in the agency’s Laredo sector. He is accused of targeting women believed to be prostitutes in what prosecutors say is the work of a serial killer.
