Ortiz was initially charged with four counts of murder, as well as aggravated assault and unlawful restraint. He has been jailed on a $2.5 million bond since his September 15 arrest in the border town of Laredo.

Authorities have said the victims were sex workers whom Ortiz targeted for their vulnerability. He was arrested almost two weeks after the first slaying after a woman escaped from him and asked a state trooper for help.
