Texas authorities have charged a U.S. Border Patrol supervisor with murdering four female sex workers during a two-week killing spree that ended when a fifth woman escaped from him and found help. Webb County District Attorney Isidro Alaniz classified Ortiz as a serial killer on Saturday.
The first murder took place September 3, authorities said.
Cuellar said investigators have "very strong evidence" that Ortiz is responsible for the deaths of the four women.
He said investigators are still trying to determine a motive for the killings.
A USA border patrol agent who authorities called "serial killer" has confessed to four murders after his arrest. The prosecutor says he feels comfortable describing Ortiz as a serial killer.
"The county, the city can rest assured we have the serial killer in custody", said Webb County Sheriff Martin Cuellar, who said he believes Ortiz acted alone. At this time, officials said they do not expect to find any additional bodies.
The sheriff's office said all four bodies have been found, and no other victims are expected.More news: At least three dead as Super Typhoon Mangkhut hits Philippines and Taiwan
The second was Claudine Luera, 42, who was found alive but in critical condition on Thursday on Texas Highway 255, according to the New York Times.
A U.S. Customs and Border Protection spokesperson confirmed Ortiz is a supervisory Border Patrol agent. Police say all his female victims were prostitutes.
"Out of respect for the victims' family and friends, we ask that deference and due process be given to the investigation so that all the facts are brought to light and they can receive the closure they deserve".

"The arrest of the border patrol agent who has allegedly committed multiple murders could not have happened without the hard work and expertise of the Texas Rangers, the Webb County Sheriff's Office, the Webb County District Attorney's Office, and Laredo Police Department".
