September 3: Melissa Ramirez
According to court records, Ortiz told authorities he picked up Ramirez in Laredo and drove out of city limits when he stopped the car so Ramirez could urinate on the side of the road.

Court documents state Ortiz pulled over and shot Luera multiple times in the head.
A truck driver discovered her body and called authorities, but Luera died at a local hospital.
September 14: Victim escapes from Ortiz
The affidavit states Ortiz picked up a woman and took her to his house. The woman said Oritz began to "act weird" whenever she brought up Ramirez's death, as they both knew her.
She said she became sick and vomited in Ortiz's front yard before Ortiz's took her to a gas station.
During the drive to the gas station, the woman said she brought up Ramirez's murder again and that Ortiz pulled out a handgun and pointed it at her.

She was finally able to get away, court documents said, and flagged down a trooper for help.
