Melissa Ann Ramirez, 26, was found dead north of Laredo, Texas, on September 4, 2018. A rancher discovered her body along a dusty road; she had been shot multiple times and investigators reported .40 caliber shell casings and distinct tire tread marks at the scene, which was described as an actual execution.

Her death was later tied to a series of murders in Laredo attributed to a Border Patrol agent, Juan David Ortiz. Another victim, Claudine Anne Luera, was found shot and later died; Guiselda Cantu and Janelle Ortiz were also identified as victims. A survivor, Erika Peña, escaped and provided a description that helped lead authorities to Ortiz, who was tracked down and arrested after a chase and standoff. Ortiz reportedly admitted the killings and said he used his service revolver.
