On September 12, 2018, 16-year-old Lourdes Sandoval, known to friends as Betty, was shot and killed outside her Greenspoint-area townhouse in Houston after sending a breakup text to her ex-boyfriend. Reports say Sandoval had ended the relationship by text after Irbin Vargas, then 22, had previously threatened her and once held a gun to her head. Minutes after the message, Sandoval left to meet a friend in a car; as she approached the vehicle Vargas allegedly emerged from the shadows and shot her in the head. The friend witnessed the attack and called for help.

Vargas fled but was later arrested by Houston police. In November 2024 a jury convicted Vargas of murder and he was sentenced to 75 years in prison with parole eligibility after 30 years. The prosecution described Vargas as a predator who targeted Sandoval during their year-long relationship.

Did anyone who knew Lourdes or saw activity in the Greenspoint area that night come forward with information?
