After details emerged regarding a Texas Border Patrol agent’s weekend arrest for allegedly killing four women, CrimeOnline‘s Nancy Grace said she there are likely more victims out there.

“You don’t go from 0 to 120mph in the space of a week,” Grace told DailyMailTV host, Jesse Palmer. “We know now there are four murder victims and a potential fifth that managed to get away half naked….I don’t think he escalated that quickly to murder. I think there are other bodies.”

Juan David Ortiz, 35,  sought out people to target, according to police, who were vulnerable “whether it be because of alcohol, substance abuse, drug addiction or prostitution.” At least four victims have been shot to death. Ortiz reportedly told police the women were prostitutes, according to the USA Today.

A fifth woman managed to escape his Laredo home after he reportedly pulled out a gun over the weekend. She called authorities immediately. When detectives questioned Ortiz, he reportedly confessed to killing four women and led investigators to their bodies.

The victims, identified as Melissa Ramirez, 29, Claudine Ann Luera, 42, and Humberto Ortiz, 28, were all shot in the head. A fourth victim, still unidentified, was also shot in the head. The murders occurred between September 3 and September 15. Investigators found all four victims’ bodies within a mile of each other.

Grace said Ortiz fits the profile of a serial killer.

“If you look back over history, for instance, BTK ‘buy, torture, kill’ Dennis Rader was married with children and seemingly living a normal life as a government employee, much the same way you see Ortiz living. Not only that, we see him exerting control over his victims. We know they were all shot in the head…He used his pickup truck in each of the cases. Typical of serial killers, they do the same thing over and over and over.”

Ortiz is behind bars, being held on $2.5 million bond. He’s facing charges murder, aggravated assault with a deadly weapon, and unlawful restraint.
