Diamond Samantha Cruz, a 21-year-old Hispanic woman from Tyler, Texas, tragically lost her life on August 9, 2020. Born on May 31, 1999, in McAllen, Texas, she was a devoted mother to her two children, Adali and Nathaniel. Diamond was homeschooled and received her education from Penn Foster. She was known for her warm personality, constant smile, and love for her children.
On the morning of August 9, 2020, Diamond was found dead at a home in the 8700 block of County Road 384 in Tyler,
Texas. The circumstances surrounding her death were initially unclear, but it was later revealed that she had been shot. Her death led to a manhunt for her partner, Catalino Castillo Marin Jr., who was the father of her children. Marin was arrested later that same day by Tyler police.
Marin initially claimed that the shooting was an accident, stating that he and Diamond had been fighting over the gun when it discharged. However, investigators found inconsistencies in his account and noted that Marin showed no signs of remorse. During an interview with the sheriff's office, Marin referred to Diamond as "the body" or "it," and his body language indicated a lack of concern for her.
In October 2022, Marin pleaded guilty to the murder of Diamond Samantha Cruz and was sentenced to 33 years in prison. Diamond's mother, Dalila Lopez Morales, attended the court hearing and expressed mixed emotions about the conclusion of the case. While she was relieved that the case had come to an end, she continued to mourn the loss of her beloved daughter. Dalila described Diamond as a loving and fun person who enjoyed shopping and dining out, particularly at Olive Garden.
Diamond's death highlighted the issue of domestic violence, as she had been a victim of abuse. Her mother hoped that more resources would become available for victims of domestic violence and that they would be encouraged to speak up. Despite the pain of losing her daughter, Dalila stated that she did not hold a grudge against Marin and believed that his ultimate punishment would come from a higher power.
