Webb County Sheriff Martin Cuellar said during a news conference that the agent, identified as Juan David Ortiz, was arrested Saturday morning, according to multiple reports.
The sheriff said that Ortiz was a 10-year veteran supervisor with Border Patrol, local NBC/ABC affiliate KGNS reported.
Webb County District Attorney Isidro Alaniz said authorities were able to find Ortiz after a woman he allegedly kidnapped tried to escape. Ortiz was captured in the parking lot of a Laredo, Texas, hotel after fleeing from state troopers.
Alaniz said that Ortiz will face four murder charges and one count of aggravated kidnapping, according to KGNS.
