According to arrest affidavits, Ortiz would pick the women up in Laredo, drive them outside city limits and shoot them. The Laredo Morning Times reported Ortiz was caught Sept. 14 when a woman escaped his car at a gas station and alerted a state trooper. The woman told authorities Ortiz had pointed a gun at her.
Authorities located Ortiz about four hours later.
The Washington Post reported Alaniz outlined why his office chose to seek the death penalty for Ortiz.
"The horrific nature of the murders. His complete disregard for human life. His vigilante mentality. He violated his oath to his country and his agency that he swore to protect,” Alaniz said. “We also believe that there are no mitigating circumstances in his life where it is justified for life without parole.”
U.S. Customs and Border Protection spokesman Carlos Diaz said Ortiz has been suspended without pay since his arrest. On Wednesday, the agency did not respond to a request from the Laredo Morning Times for an update on his employment status.
