Maribel Cruz was a 43-year-old mother and a respected research professional who lived with her family in southeast Houston, Texas. Neighbors knew her and her husband as calm, nice people who would offer a friendly wave. They were not known to be violent, and if arguments happened, they occurred behind closed doors. To the outside world, they were a quiet family.
The tranquility of their home was shattered in the early morning hours of Sunday, October 19, 2014. At around 12:45 a.m., some of the children in the house, whose ages ranged from one to 20 years old, heard sounds they later described as gunshots. Unsure of what they had heard, and having heard no argument, they checked on their mother. Peeking through a window, they saw Maribel lying in her bed and assumed she was simply asleep. Believing it might have just been a toy pop gun one of the younger kids was playing with, they returned to their own beds, unaware of the tragedy that had just unfolded in their parents' bedroom.
Hours later, around 7 a.m., the eldest daughter, who was 20, was preparing for work. She noticed that her stepfather's pickup truck was still parked in the driveway, which was unusual as he was supposed to have left for his job by 4 a.m. A sense of unease prompted her to check on her parents. She found their bedroom door locked. After getting a key to open it, she made a devastating discovery. Inside the room, both her mother, Maribel, and her stepfather were dead from gunshot wounds.
The Houston Police Department (HPD) was called to the home, and homicide investigators began processing the scene. The investigation concluded that Maribel Cruz had been the victim of a murder-suicide. Detectives determined that her husband, identified in one report as Raul Cruz, shot and killed her before turning the gun on himself. HPD Homicide Investigator Robert Lujin commented on the children's initial reaction to the gunshots, stating, "they didn't think anything of it till this morning." An autopsy was ordered to officially determine the causes of death.
The news shocked the quiet neighborhood. Neighbors expressed their disbelief, recalling the couple as peaceful and friendly. "From what we know they were calm people," one neighbor, Lewis Snyder, told reporters. Another, Adrian Lewis, who had heard three gunshots the night before but thought they came from a distance, said, "They were nice people, I saw them very often... They would come around the corner and do little waves, you know." The community’s thoughts turned to the children who were now left without their parents. "It's sad that any kid would find out that their parents are no longer with them," Lewis said.
Because investigators determined the case to be a murder-suicide, no outside suspects were sought, and no arrests were made. The Houston Police Department considered the case closed following their investigation in October 2014. The motive for the tragic act was never publicly released by law enforcement. The focus shifted to the well-being of the children who survived this profound loss.
