Olga Guadalupe Guevara, a 30-year-old Hispanic woman, tragically lost her life on December 31, 2020, in Donna, Texas. The incident occurred during a New Year's Eve gathering at her residence. Olga, along with her 58-year-old mother, Maria de La Luz Reyes Martinez, was found dead inside the home. Both women had suffered fatal gunshot wounds. The Hidalgo County Sheriff's Office responded to the scene following reports of a domestic dispute and gunfire. Justice of the Peace Jason Pena pronounced both women dead at the scene and ordered autopsies to be conducted.
The investigation revealed that the suspect in the case was Olga's common-law husband, 29-year-old Agustin Adan Castellano. According to authorities, Castellano shot both Olga and her mother during an argument that escalated into violence. The altercation began as a verbal dispute and quickly turned physical, culminating in the tragic shooting. Castellano was arrested at the scene and charged with capital murder for the deaths of Olga and Maria. The charges of capital murder are severe, as they carry the possibility of the death penalty under Texas law.
The case garnered significant attention within the local community, highlighting issues of domestic violence and its devastating consequences. Castellano's arraignment took place shortly after his arrest, and he was held without bail due to the gravity of the charges. The legal proceedings against Castellano continued as the community mourned the loss of Olga and her mother. The Hidalgo County Sheriff's Office urged anyone experiencing domestic violence to come forward and seek help, emphasizing the importance of addressing and preventing such tragedies.
