Ortiz, a Border Patrol intel supervisor at the time of his arrest, was accused of killing Melissa Ramirez, 29, Claudine Anne Luera, 42, Guiselda Alicia Cantu, 35, and Janelle Ortiz, 28.During the trial that began last week, jurors heard Ortiz’s confession during a lengthy taped interview with investigators.Ortiz told investigators he had been a customer of most of the women, but he also expressed disdain for sex workers, referring to them as “trash” and “so dirty” and insisting he wanted to “clean up the streets.”He said “the monster would come out” as he drove along a stretch of street in Laredo frequented by the women.Defense attorney Joel Perez argued that Ortiz, a Navy veteran who had been deployed to Iraq, was suffering from post-traumatic stress disorder, had been suffering from insomnia, nightmares and headaches, and was medicated and had been drinking that night.The bullets collected from the crime scenes came from the same gun, and matched the weapon found in Juan David Ortiz’s pickup, a ballistics expert testified."
